Thirded. And as huge of a Batman fan as I am, I'll say that Cap's trilogy is better by far in terms of enjoyability for me.
Fourthded?? For me, I found BB the best of the series, and as it got darker in tone I found it less enjoyable. I love Heath Ledgers' work in general, but (for me) I would take Jack Nicholson's Joker over TDK's Joker every day of the week. The Cap trilogy (again, for me) started out slow (Cap 1 was my worst rated movie from the phase 1 movies), however Cap 2 was the best phase 2 movie (IMHO). Cap 3 turned it up to 11, and (unfortunately) for DC, showed them how to do an ensemble movie.
