Just been to see the Dark Knight. Keep wanting to add a Returns to that. The comic book genre really has grown up with this one. Outstanding performances from pretty much everyone, not just Heath Ledger, although his Joker is outstanding. This is the movie I wanted to see when I went to see the first Batman movie.
It seems to draw heavily on some of the best Batman comics from recent years, including Dark Knight Returns, The Long Halloween, Dark Victory and Killing Joke. If you liked the movie and haven't read any of these, I think you might enjoy them.
If this is what we can expect from upcoming comic book movies, then I for one will be very happy - even if the movies themselves might be a bit bleak.
