I never realized that Mask of the Phantasm was based off a Batman comic called Batman Year 2: Fear the Reaper which was a sequel to Frank Miller's Batman: Year 1. Although I don't think it follows the plot too closely.
The Batman Animated series also was responsible for one of the best video game adaptations of a TV property. The Adventures of Batman and Robin on the SNES. I loved that game and even with today's gaming standards, it's still a good game.
The funny thing about the Batman animated series is that they handled a lot of the lesser known villains better than some of the more famous. Maybe that's because the lesser villains had been so underdeveloped in the past. But Catwoman, Penguin, The Riddler, and even the Scarecrow just seem to lask something. Part of it might have to do with the fact that most of the episodes they appear in are too fantastic or lame. Some of the best episodes were when a villain was being introduced for the first time. Mr. Freeze, Clayface, The Ventriloquist, The Mad Hatter, Two Face. Even the Clock King. I love that guy.
I still have hopes for the new Batman movie. It's the movie I most want to see in 2008. Even if Indiana Jones comes out and there's another James Bond movie. The Dark Night is still the one I am most interested.
