I was expecting major Amature Hour, but I actually thought both actors did a decent job.
Although I might just have been impressed that LTT basically looked and acted how I pictured him...and that rarely happens. Usually characters in adaptations don't seem anything like my mental pictures of them. Ishamael certainly didn't, but I thought the guy playing him was convincing nonetheless (other than a couple of spots where I thought his delivery was weak).
I also liked how they let us get to know LTT's family just a bit, even if they were basically just stock characters. It's still more than we got in the book, where sometimes I forget LTT even HAD children, since he never talks about them and only cares about his wife.
Also liked how they portrayed the bodies as dolls while LTT was still nuts, and how the sheer number of them all over the place began to clue him in that something was wrong, even before Ishamael healed him.
Of course, it sucked that they didn't include the formation of Dragonmount, but this was obviously made on a shoestring budget, and they likely couldn't afford decent special effects and I'm sure it would have looked incredibly stupid done with cheap effects (the one time they showed channeling, it looked cheesy as hell).
That said, I didn't think it was anything to write home about, just impressed that it was better than I expected. I still hope RJ's wife gets the rights back and sells them to someone who might actually do something with them.
