Let's see… The MPAA rated this R for "strong violence and language throughout, sexual references and brief drug material". That understates it a bit. I waited until Mrs. Salad was out-of-house to watch it.
Mr. Pool, played by Ryan Reynolds, gets a quick comedown from the happily-ever-after ending of Deadpool, when Vanessa (Morena Baccarin) gets seriously killed by (yes) a guy that Deadpool let live in a previous scene. Those guys always come back to get you.
After a gruesome suicide attempt, Deadpool joins up with X-Men member Colossus to perform a goody-two-shoes X-Men-style mission: rescue a misbehaving kid from a mutant re-education center. This is complicated somewhat by Cable (Josh Brolin), a visitor from the future, back to avenge/prevent the deaths of his family at the hands of the future kid. And then…
There's a considerable amount of fighting and imaginative special effects. In addition to the aforementioned violence and language, there's a lot of fourth wall breaking and myriad references to other movies. (Someone should count them.) (Should? Some nerds probably have counted them.)
Not recommended for the easily offended. Or even the uneasily offended.
