Just saw Guardians of the Galaxy this morning and it was awesome! I will not post any spoilers, but I will say I was disappointed in one super-minor (and highly personal) thing. I'm normally not that observant, but I spotted a hilarious Easter-egg that was only on the screen and in-focus for a split-second....short enough for me to question if I saw what I saw. My suspicions were confirmed in the after-credits scene.
Also, this is what, the 10th modern Marvel movie? Who the hell bothers to get up and leave the theater when the credits start to roll? Evidently some folks in Boise, that's who.
