Well, he spoke well. Um...that's about it.
I didn't particularly like TDKR. All three movies were a bit long and pretentious, but TDKR too it way too far.
A lot of the movie could have been trimmed, and that was particularly annoying because there wasn't enough Catwoman. Finally, Batman gets to interact with another costumed person that's sorta kinda on his side...which, IMHO, is the best thing about Batman. On his own he's not great, but with a masked partner or sidekick or ally (police aren't quite the same), he can work. And Catwoman doesn't really do much, giving the movie is close to 3 hours long.
Anyhoo, IMHO, Bane didn't work well because the movie didn't. I coudln't take the movie seriously, so I coudln't take him seriously. I think it would have been better to make it silly and campy, have cackling supervillains and get Catwoman making terrible, terrible cat related puns all the time. If you movie is going to be very silly, at least acknowledge it.
