I think this might be the darkest feeling Batman movie yet*. I mean that in the best way possible. I want dark & angsty emotions when I see a Batman trailer. It's not an uplifting property (even though I adore and cherish Adam West's stuff, that's more nostalgia with my Grandparents). So far, in my opinion, the FIRST appearance of each Batman since 89 has been great, it's the follow ups and ability to continue that has been the real bugger, Christian Bale aside (I loved DKR). I think Mr. Pattinson is going to do well.
*not an academic on comic book medium at all and my only knowledge is from the movies I've watched and the discourses I've had online.
