I am not sure that means much to me, I hope it is good, but a part from potentially Batman Begins I did not find the movies to be that great and Dark Knight Rises I thought was bad.
Dark Knight was good, but almost totally because of Ledger's Joker in my book. If he was not in it I do not think it is half as good or memorable.
Just my two cents though, I hope the new movie is enjoyable enough though. Pattenson is a pretty good actor really and has done alot to dig out of the whole Twilight thing. Lighthouse was particularly good.
Ledger was a once in a lifetime acting role, so the bad news is that he tainted any and all performances of the Joker to come after him, so maybe best to never see Joker on the bat movie?
