Batman/ The Dark Knight
Batman Forever (after many years of holding my nose up at it, I've recently warmed up to portions of it--it is still problematic, but has some decent material in there)
To be candid, I wasn't all that receptive to The Dark Knight Rises. It's a well crafted film, no doubt, and I certainly don't fault folks for enjoying it. I just didn't feel like I was the film's audience.
Batman and Robin: I recently tried to watch this, but just couldn't.
I'm not sure where to put Batman 66. It's probably still toward the top, but I feel like it needs to be in an entirely different category given the drastic difference in tone and world of story.
