This film has all the great cross-over action scenes we've been waiting for. Each character gets a time to shine and dialogue that fits them well. If you haven't seen all of the other movies leading up to this I think most of it will still make perfect sense, but you'll miss some quips and inside jokes. Also, be aware that while this film is mostly fun there are some much darker moments, including a torture scene. All in all, though, the film is certainly worth the hype.
