about 20 minutes into the movie, I turned to my bro and told him "dude, this is already a better flick than the first one". My beef with the first was that it was very underwhelming, and quite heavy-handed in the way it presented the characters. Here, we already know the characters, so the action can start straightaway.
Without spoiling it for anyone, a lot of very-well shot action sequences. An acceptable corniness level (eps. for a summer flick). Brian Cox, as William Stryker, is great, as is Alan Cumming as Nightcrawler.
Go see it
