I actually fell asleep for a few minutes during one or two of the fancy actions scenes. But I might just be a jaded old dude.

Some parts were kind of sort of funny. Overall, meh. Really most of what I liked involved the what, 2-3 minutes of screen time that Thanos got.

Oh and the after-the credits scene is probably the worst of any Marvel movie. I recommend everyone save yourself those extra minutes of waiting in the theater. It's dumb, and a total waste. After doing such a great job of having the after-the-credits scenes tease us for the next big Marvel flick, this and Iron Man 3 totally dropped the ball with that.
