Which is pretty much as far apart as any two movies out in theaters at the same time can be - popcorn blockbuster vs a European arthouse movie that is meta even by arthouse standards (most of the plot focuses on rehearsals for a stage play).
I went for Clouds, which was very good, albeit even trickier (as in, not giving you all the answers directly, if not being downright enigmatic) than I had expected - and yet more proof, if we needed any, that Kristen Stewart is a fine actress, Twilight or no Twilight. Juliette Binoche is arguably the bigger surprise of the two, though. And the director actually got in a pretty good dig at superhero blockbusters by showing the pair of them going to see the superhero movie that made Chloƫ Grace Moretz' character's career, of which we see a clip in which he rather satirizes the genre - followed by a scene in which Stewart tries to defend the merit of the movie against Binoche's ruthless mocking and fits of laughter.
But yeah, as for Guardians, maybe next time.
