There is one thing that kind of really bugged me (big spoiler so I'm white texting it):
The death of Bane. When I saw it I just kind of assumed he died because Batman was harming his mask and he was going crazy, but thought the film never addressed it. It wasn't until afterwards when I read some other things when I realized Catwoman killed him when she rescued Batman, but that's basically a blink and you miss it scene. I'll pay more attention next time I see it, but I'm surprised by the lack of focus on such a big deal.
Yes, given how big a character he was his death was almost missed. While he got thrown to the wall when Selina burst in, that hasn't stopped him before, so it seemed as if a scene was missing.
