Best summer movie since the X-Men reboot, and it was a good thing, too. They have been sticking hints and previews into every Marvel movie for the last few years.
Did they pay it off?
Yeah, the story is thin, and the characters not really deep either, unless, of course you have seen those movies featuring Thor and Iron Man and Captain America and the Hulk, which, if you are a fanboy, you have, so you come equipped to accept the characters for who you already know they are.
Loki is back, and bad as ever, and the high-tech whiz-bang stuff goes whiz and bang in spades.
For the first time ever, Bruce Banner and The Other Guy, as he calls the Hulk, steal a movie. The two best lines in the picture are directed at the Hulk: One, by Captain America, and every fanboy in the world screamed and laughed when they heard it. The second is when Loki has something to say to the Hulk and if you don't laugh, your humor bone is broken beyond repair.
Everybody gets a super-hero turn, and they all kick serious ass and take names, exchange witty remarks, and by all means, stay until the last credit rolls for the tag. (There are actually two tags, once showcasing a possible villain, one funny one.)
Worth the trip.
