Would Anyone Care if it Wasn't About Batman?

Rating: 1/10 (12 October 2017)

I'll try to keep this brief.
Here's what I want all of you die-hard Nolan Batman fans and comic book geeks to try to imagine:
Imagine that Heath Ledger wasn't wearing clown makeup and that Christian Bale wasn't wearing a bat costume. Then try imagining if this movie wasn't based on your beloved superhero.
Would any of you still think it was a good movie or that it was even remotely well acted? Would it really rank #4 on IMDb greatest movies of all time?
