‘Deadpool’Deadpool, Ryan Reynolds’ second crack at Marvel’s most in-your-face character (following a forgotten appearance in the misbegotten X-Men Origins: Wolverine) is a terrifically faithful adaptation of some awfully obnoxious source material. If you’re a pre-existing devotee, the film’s nonstop assortment of cartoony assholes and elbows to the ribs might very well make your head pop off in a paroxysm of joy. (Seriously, the employees at the crammed preview screening I attended probably wished they had put down plastic beforehand.)
