I highly recommend watching the first part of Batman: The Dark Knight Returns (you can even check out my review right HERE) before enjoying Part 2.
This movie is set some time in the future, with a much older Batman having just returned from retirement.
It has been 10 years since all super heroes have been basically outlawed.
If you watched the first part, I'm sure you're dying to see how it ends, so GO WATCH IT NOW.
If you still haven't watched the first part, are you hard-headed or something?
QBF Rating: 5/5
PS: Check out Frank Miller's graphic novel The Dark Knight Returns which this is all based on, and its sequel The Dark Knight Strikes Again!
