Yep, I got into an advance screening, and the movie was amazing. It combines the best elements of movies like
Natural Born Killers,
the Matrix,
Kick-Ass, and other ultra-violent CGI-enhanced movies into the most ridiculous over-the-top superhero movie ever. I'm not deep enough into the Deadpool mythos to tell you if every character is 100% accurate (I mean, Al and Weasel felt like Al and Weasel), but Deadpool definitely felt like Deadpool and Ryan Reynolds did an amazing job. If you have any doubts, ignore them. This movie is THAT good. It's "Itchy & Scratchy" as if done by Zack Snyder.
(OK, one nitpick: Colossus looked terrible. His arms were about a foot too short and he just looked and acted wrong. He provides some comic relief, but he really came out of the oven way too early.)
I've got more thoughts up (along with a cohort) in
this review, which does get a little spoilery. But, seriously...go see this.
Don't take your children.
