I wouldn't say garbage, nowhere near worthy of the hype and praise though.
As it is it was an average movie when viewed in isolation, as part of the trilogy it was the weakest of the three, coming from a director of such pedigree and with a solid cast it could and should have delivered so much more.
It was sloppy and loose, tiresome and poorly paced, it felt cobbled together and rushed almost as though it had been through three different writers or directors.
Bane was dire in every aspect, it demanded nothing of whomever played the role other than to be big, and and tom hardy wasn't big enough!
There have been complaints raised about not seeing his mouth, making dialogue hard to follow and losing any emotive qualities. All valid and true points, when I watch a movie of any genre I should not have to focus intently on one characters lines, it is not a flawed idea and can be done brilliantly.
Darth Vader in the original SW trilogy wore a complete facial piece, not a hint of emotion could really be conveyed in traditional methods and yet through tight direction of David Prowse and clever dubbing of James Earl Jones it carried more weight and intensity than than Bane could ever hope to.
I could dissect the movie further but it'd really not worth it, I love cinema, adore suspending reality for a while and losing myself in an alternate universe. I enjoyed BB and fell in love with TDK, but cannot find anything positive to say about TDKR, and 4/10 is the best I can muster, even that feels generous.
