I find it funny that many of the complaints are about plot details, yet I've seen many imply making it a little bit prettier/brighter would have made things better. And nah, I think the way it's handled fits the tone just fine. I don't mind it.
Bane's way more skilled, so he's going to land more hits, but even with the strength boost, he isn't as durable and he doesn't have an accelerated healing factor. Either he ends it quickly and brutally or things drag on and he suffers a savage defeat.
