“Deadpool” (**1/2) was an over-the-top but fairly entertaining comic book action thriller about a smirking vigilante (Ryan Reynolds) who finds out he has terminal cancer and is reborn into a crime-fighting superhero bent on saving his city from destruction. Occasionally funny but also occasionally silly and sometimes too flip and too cute for its own good. Reynolds’ performance ranges from fun to annoying. He needs to realize that acting doesn’t always mean being the coolest guy in the room. A mixed bag but worth it for comic-book fans.
