Going in without any real expectations, this 60 minute vintage mystery-comedy delivered exactly what I wanted: all of the above. Weird in a great way.
I don't think this could have completely lived up to my expectations. While I didn't enjoy it quite as much as The Dark Knight, I also don't have a list of changes I wish Nolan had made. Something about this being even more epic than the previous pictures worked against it (probably related to an increased suspension of disbelief), but it still mostly delivered what I wanted from the final installment of this Batman's story - a capable villain, a layered story, intense action, and an overall demonstration by the filmmakers that they care about the characters and ideas at play here.
