Cable has come back through time to assassinate a youthful Firefist. Deadpool is in the way.
Yes the sequel is as funny, irreverent and determined to destroy the 4th wall as it's predecessor. The characters are great and the effects eyepopping. Storyline is really awful though.
Well, yeah the plot is stupid - it's based on a Rob Liefeld comic. We're not talking high points of Augustan literature here. It's fun and gleefully hateful at the same time, perfect for the wonderful times we live in.
