I do agree with some of your points. I do think there were a few things that were glossed over for time. It's important to remember that the original script for this film was 400 pages long. I would guess that certain things like Bruce and Talia's romance and Daggett's attempt to control Wayne Enterprises would have been covered in further detail. I also agree that Modine was unnecessary.
As far as Robin goes, I admire the ballsiness of Nolan on that one because whenever you change a character that drastically, you're gonna hear it from people. I do like that he seemed to be a combination of different Robins and was in a way raised by Bruce. Through the orphanage.
The Batman voice was better in this film than the last one, I thought. It's funny, when I watched Batman Begins again I noticed how much less growly his voice is in that movie. It's way overdone in The Dark Knight and then it's kind of in between in this movie. The only part that made me laugh was at the end when he had finally beaten Bane and was trying to get information out of him. "WHERE'S THE TRIGGER!! WHERE IS IT!!! WHERE'S THE TRIGGER!!!" Though I did like the reversal of the "you'll have my permission to die" line.
I'm glad you brought up the extras in the movie being played by known actors. Two other guys you forgot to mention were Quin from Dexter and the guy who played the president. While distracting at first, I was glad for it. One of my beefs with The Dark Knight was the horrible acting by some of the extras. The whole scene were Dent addresses the media about Batman turning himself in. The boat scene at the end. A couple other parts too. If it comes down to horrible actors or guys I've seen here and there before, I'll go with the latter.
Tom Hardy's accent wasn't English by the way. Or at least, that's not the intention. TDKR: Tom Hardy Reveals That Bane's Accent Is Based On "The King of the Gypsies"
Glad you liked the movie overall. I did say before that I thought the second viewing was much better. There is just too much audio and visual stimulation in this movie to catch everything the first time. Especially if you try to make the connections with the previous two movies.
Edit: Also forgot to mention that I agree that Nolan asks us to suspend our disbelief a little more in this movie than the last two.
Too many "known" actors as extras? I guess I don't watch enough TV. LOL.
Saw it today again and among the 'actors who looked familiar' for me was Bane's #2... from "No Ordinary Family" (Josh Stewart?) and the Army Captain squad guy who doesn't last very long before getting a tour of the bridge via rope.
On the topic of 'Alfred at the end', it looked seamless to me, so unless someone mentions it on the BD commentary, there's no way you can convince me that any of that scene was "off". :)
All I know is that it was thoroughly enjoyable seeing Franco get riddled with bullets.
