This is a really, really, fun movie. None of it makes any sense. Continuity falls by the wayside. On the other hand, lots of big-name actors, even just in cameo roles, and beautiful fight choreography. You can tell it was a lot of fun to make this movie.
If you want a thriller, pass. If you want to point and laugh, and try to catch all the jokes and puns, go for it. If you care about continuity, this movie is probably not for you. If physics matters to you… No.
But if you just want a fun movie to watch, this is not a bad deal at all.
