Batman: TAS probably still is my all-time favorite action/adventure animated series. It might be my favorite action/adventure series in ANY genre/medium, period!
Before this show aired in 1992, action/adventure -- especially superhero shows -- just weren't that intelligently written let alone designed well in most cases! They were awful because of preconceived notions about what kids could tolerate and the condescending views of the population at large towards comic book characters. In a word, pre-1992, animated superhero shows were mostly geared (it seems) towards retarded audiences! It was that bad...
Post-1992, we have much better-written animated adventure series as well as shows with distinctive art styles instead of the cookie-cutter stuff that had been going on since the 1960s.
Now, I'm a bigger fan of the '92-'95 Batman AND Mask of the Phantasm than the Batman that followed it. (I just don't like the 1997-1999 character re-designs much and the writing wasn't as consistent as the earlier series. Some good episodes, there, yes, but a few stinkers, too!) It really was a Golden Age for Batman in general and I like this version of the character far better than any of the live-action stuff since 1989 and far more than what's been in the comics (excepting the animated spin-offs!) since 1986.
As I said before and promised another guy in a PM, I will try to put up thumbnail links of the statues that I own now. I have all the official maquettes based on the Timm-designed series = Batman: TAS, Superman: TAS, Justice League/Unlimited. I also have the Fleischer Superman and Lois Lane that were released a few years ago, too..
As much as I liked Superman: TAS (1996), it still doesn't hold a candle animation-wise to the fantastically done Fleischer theatrical Superman series of the early 1940s. Media companies just don't want to put that kind of money into a superhero animated project which is why most production work is outsourced overseas... mainly with Korean animation studios now. Japanese studios were used for some episodes and a few of the movies in the 1990s but I haven't noticed that much Japanese work since then.
