Which is why I appreciated the short-but-sweet fight with Harry. Lunatic in a combat suit on a horribly designed flying thing, been there, seen that, so they came up with some creative staging, and Holycrap! actual physics and anatomy suddenly rearing their heads in a comic book film about people getting superpowers from the bites of magic spiders and eels.
You forgot overly long, with a kind of Saving-Private-Ryan drag between the excellent opening and closing fight scenes. Also, the seasonal mourning shot. Anything "Twilight" has already done is something you should be pretty confident about leaving on the cutting room floor.

Which one? Just out of curiousity? Harry was pissed that Spider-Man wasn't helping him, then discovered his friend had been misleading him. He's a spoiled rotten rich boy with a corresponding entitlement complex, and either the green juice or his illness could be having an effect on his brain, so the reasons don't have to be good, just make sense to a whack job who thinks he should get whatever he wants. And Max was also a few screws loose, and fixated on Spider-Man to a blatantly unhealthy degree. The idea of a stalker turning against the object of his unrequited obsession is hardly unknown. Regardless of the psychological reality, it's a firmly established law of Movie Psychiatry.

I thought the film could have been a lot better if it hadn't spent so much time on the cartoon stereotype of a nerd, presumably trying to hit all the designated checkpoints on the comic book character's origin story. Or at least made his appearance and non-psychotic-obsessive behavior more normal. Aside from his idea that the company stole without intending to give him credit, you'd think a company that has security guards in the room before you finish running an unauthorized employee directory search would have had a potential lawsuit or ticking time bomb like Max excised post-haste, instead of tormenting him Milton-from-Office-Space style.

And speaking of which, Oscorp is not very inspiring a villain, are they? Regarding that security guard incident, first they overacted, then they let Gwen get away fairly quickly and gave up on her once she was in the elevator, like she had touched base in a game of tag. Also, do the security guards on each floor have some sort of non-communication policy with the others? There should have been a cordon of guards ready to stop Gwen in the lobby. Real law enforcement's unofficial motto is "No one can outrun a radio." The sensible thing would have been to make discreet inquiries as to the point of Gwen's interest in Max, and if she shows signs of being a whistle-blower or snoop, instead of a mere concerned coworker who is wondering where the odd dude in the elevator went, THEN you snuff her out. You don't let her waltz off to England on a scholarship that your own company set up for her. In any other movie, the moment she heads out the door, Her Life Is Over (kind of like with Peter's parents). And also, don't have the protagonist of your movie make jokes about how cliched hiding in the maintenance closet is, if that is what your daring escape from security relies on! I mean, checking the closet is the ABCs of tracking down a fugitive.

Also, how did one of their top scientists, who had the owner's presumptive close attention, manage to conceal a hidden underground base from the company? What, did they just throw some funds for a facility at Parker Sr, and say "go build whatever you want, and work whereever you want, with the highly valuable cure for a disease that is afflicting our top guy, and which could be used to save millions and millions of paying customers. Don't tell us what you are doing or where you are setting up. We prefer to be surprised."

Either that, or he was working in a hidden Oscorp facility for 10-11 hours a day, and Oscorp forgot about that base. They can hijack the man's private jet to steal his data, but they can't go looking in the Cybertronian lab they built for him, to which he was sending a copy of said data anyway?

And who the hell built "Roosevelt" if Oscorp didn't? And for that matter, where did Parker Sr get the money for a private jet, or was he dumb enough to try fleeing his employers with the company plane?

Either that whole backstory was the result of the actions of the world's dumbest but most innovative and productive corporation, or dumbest but most brilliant scientist in the history of the field. Or some combination thereof.

And the police make a late showing at the end for the Idiot Prize, after spending much of the film fading out of contention but not actively trying to impede or interfere with Spider-Man. They even demonstrate a rudimentary understanding that they are out of their depth in certain situations, and allow Spider-Man to take the lead. But then, in the final confrontation with Russki Rhinosuit, where Russki keeps pausing in shooting up a street to pop open a huge hatch in his armor to taunt the cops, show his face and shout his name in the midst of a gun fight and bank-robbery, they decide to play by Marquis of Queensbury rules, and hold fire, at least until he calls "time in" by withdrawing back into his impervious walking tank to resuming hosing the area with automatic weapons. Then, when the stupidest kid in the city (who demonstrates as much by advocating wind turbines and assuming a costume gives him the ability to fight armed supervillains) slips away from his mother to confront Russki, the cops restrain his mother from chasing him, while letting the twerp walk past them! Did they assume he was a diversion so his mom could do something sneaky? Because common sense suggest that grabbing the kid would also bring the mother under control as well, no? Or maybe, in keeping with every freaking character in the damn film being a scientist(even Aunt May gets a nursing degree), generally of the "mad" variety, they snapped into eugenics mode by deciding that any kid dumb enough to wander into a firefight with a suit of powered armor, much less the spawn of a mother who watched a shootout from the edge of the barricades, child in tow, rather than beat feet for home, or at least around the corner from the gunplay, was someone the gene-pool really didn't need.

The rhino armor guy was the biggest letdown since "The Grey". But regarding the Marvel Studios thing, aside from Stan Lee's appearance, they are not really connected. Sony owns Spider-Man, and has nothing to do with the Avengers. I read recently that this is why there is no mention of him showing up to help out the Avengers during the alien invasion of his own city, and that there are a couple of mutants on the Avengers in the comics who are going to be in Avengers 2, but will not be referred to as mutants, or by their names, because the X-men filmmakers own the rights to those characters, as well as the Marvel concept of mutants. From the X-men preview in the credits, I am assuming that they are the same studio that owns Spider-Man, so he could deal with mutants and stuff like that, but not the Avengers, nor can SHIELD get involved with the mutant round-up or crackdown, as you would assume would fall into their jurisdiction from the Avengers films or the TV show. IDK where the less successfull Marvel films fall, like Ghost Rider, Punisher, Daredevil or the Fantastic Four. Probably not with the Avengers for that last one, which would explain the casting of Chris Evans in both franchises.

BTW, a trailer I saw before this film showed an X-men character who was really really fast. Might he have been one of the pair in cells in the post-credits scene from Thor 2 or CA:Winter Soldier, whom I mentally labeled SeizureMan?

Again, mega-disappointment, as the previews made a much bigger deal of Ira Gaines stalking about in his trenchcoat, like some sort of behind the scenes mastermind out to take down Spider-Man.
