Eyy! Caught a showing of Guardians of the Galaxy. I thought the other Marvel movies I've seen were OK-to-mediocre (IM1, IM2, Avengers, Thor, half of Captain America), but this one was actually really cool and worth seeing! Much funnier and better written than the others and WAY prettier to look at (lots of really cool space vistas to look at). All the characters were pretty solid and I think not knowing who any of them were made things more fun and surprising.
Also, the post-credits "stinger" for these movies is usually a labored tie-in to some future entry in the series, but this time it was just ludicrous (in a good way).
