Gripes:
Bane's death was cheaaaap, also convenient plot device to beat him, and his hell on earth prison didn't seem that much of a hell-hole
Characters knowing everything without it being clear how they acquired knowledge
People always turning up in the right place at the right time
The doomsday weapon's plausibility was very similar to the device in the first film, and also they hyped up the whole energy thing then left it, along with Fox and Wayne Enterprises in the dust, which ties into...
How is JGL supposed to take the mantle without 1337 martial arts training and unlimited funds?
The Florence thing at the end - I embraced the cheese, but poor Alfred never got to make up with Bruce after their spat and parted on bad terms.
I didn't know about the Talia twist, didn't see it coming either - but was very relieved when it did, since when Bruce hooked up with her it was v. contrived and they lacked any kind of chemistry and I was fearing they'd float off into the sunset when him and Selena had much more of a dynamic, hooray for shacking it up w/the one in leathers.
Anyway, gripes aside, it was a pretty damn good film and a much better third act than all the other superhoer attempts. I left the IMAX happy.
