I love the idea of it, the biggest letdown in the film for me was the execution of it. It was way too sci-fi and it felt like a video game, the way it panned everywhere.
Still love the movie, but it would have been much more effective if it was simpler.
The sonar/lenses had a purpose and it was executed. I don't think we will be seeing them again. I didn't mind them one bit though. But I agree that Bale's eyes are much more menacing then lenses.
the sonar sequence was way too flashy. Didn't like his sonar lenses. Overall I'm 'meh' to it. I liked the idea but not how it was executed.
It was a great idea but it came off as a video game with Morgan Freeman playing Morgan Freeman narrating. Bad guys to your left, boom, now on the next floor, bang, Joker is on the 3rd floor, pow. When all Batman had to do was tell Gordon that the hostages were in the clown masks or even tell a soldier so he can tell everyone...instead he beat up the good guys.
This was the weakest plot element in the film.
I would've rather it didn't exist, and Batman relied on actual detective work to find The Joker's location.
