Saw it Saturday. While not the best superhero movie of the current generation, it's everything you'd want to see in a Deadpool movie: gratuitous cursing, quite a bit of nudity, 4th wall breaking, actually funny jokes, and a ludicrous amount of violence.
I'd suggest it to anyone who asks if it's worth seeing in a theater.
Despite the freezing temperatures (it was cold inside our theater) it still had the highest opening weekend take for an R-rated film ever, as well as the biggest February opening weekend ever.
The film's budget was $58 million. It made $135MM over the weekend.
