Animation:
Mask of the Phantasm - Need I say more?
Batman & Mr. Freeze Sub-zero - Arguably the best movie with Mr. Freeze in it, if that counts.
Mystery of the Batwoman - Not so much a mystery, but what can one do about it?
Batman vs. Dracula - Absolute horseshit. Can remember anything from it, other than Alfred looking bored.I take it you haven’t seen Batman Beyond - The Return of the Joker then. Check that shit out for sure. My favorite animated Batman flick and actually my second favorite overall Batman movie.
I was never awfully interested in Batman Beyond, but I did see the flashback sequence, which is great.
I suppose we could also include the 3 part episode Batman And Superman: World’s Finest, since it’s advertised as a movie in some places. It was a mountain of meh.
