They fucking nailed it!
Lots of awesome references to the show and in-jokes, but it still felt up to date and not totally cheesy. It was obviously a little cheesy, but in a fun way - the movie didn't take itself too seriously but it also wasn't a piss-take, either. My sister (four years younger than me) didn't remember much about the show but still really enjoyed the film.
They cast it pretty much perfectly. Liam Neeson (who is fucking awesome, btw) played a more badass version of Hannibal, but managed to stay true to the character. Bradley Cooper pretty much is Faceman anyway, so he was perfect for the role. Even his real life name fits. I'd been a little worried about Rampage's B.A., cuz Mr. T is a pretty hard act to follow without either imitating him lamely or reinventing the character, but I was very pleasantly surprised at how good he was. And Sharlto Copley's Murdock was probably my favourite part of the movie. He got the annoying but appealing and crazy as fuck mixture just right.
The plot was fairly simple but entertaining, the special effects were solid, and while it was obviously pretty unrealistic there weren't many, "oh come the fuck on" moments, a la 'Wanted'.
It's not some groundbreaking cinematic experience, but if anyone was looking for that from The A-Team movie then I guess they got what they deserved.
Two thumbs up. I fully recommend it, and will be buying it on Blu-ray when it comes out (which is pretty much the highest compliment I can give a film, considering what they cost here).
