So watched this again.
It was still funny, but for different reasons. Opening night the audience is just too loud and the jokes are just too dense to catch them all. IE when Deadpool is talking about looks not mattering, DP makes a joke about david beckham, but then immediately followed up by "Do you think Ryan Reynold's got this far from his superior acting skills?". Opening night I completely missed that bit because everyone was laughing so hard at the beckham joke. shit like that.
Also on 2nd viewing the pacing felt better. Like you knew when the jokes were coming and were prepared for them. This allows you to appreciate all the action and drama elements. This movie sure, primarily it's a comedy I suppose. First time viewing it, it's probably one if not the funniest comedies i've ever seen (not just funniest comic book movie, funniest period). But on subsequent viewings you can actually appreciate all the action/fight scenes more, I didn't realize the extent of the brutality and just how well the action was shot the first time around, it took a back seat to all the laughs, but this time I got to experience all the visceral bits of bloodshed and damn was it good.
So yeah. As a comedy it's golden. As an action movie, it's golden. As a comic book super hero origin story, it's decent to good. I mean the way it's told in the non-linear fashion via flashbacks and signature 4th wall breaking is refreshing for what is, ultimately, a somewhat run of the mill generic comic book origin film, so even there it's golden.
The fact that it does all 3 things so well is really what cements this film for me. I don't know where I'll ultimately rank it as far as comic book adaptations go, but it's somewhere in the top 3 along with Avenger's 1 and The Dark Knight.
