The way that I rank the Batman shows is strange...Its undeniable that Batman: TAS is one of the best animated shows to ever come out of the states (that even holds up today), but I have a hard time ranking TAS, New Adventures, and Beyond due to how each one has elements that I love, and got me through various stages of my childhood.
For example, I prefer Mr Freeze and the Batman costume from New Adventures over the blue and grey suit from TAS, but I feel like all of the other elements from that show are not as memorable as TAS. It's also the weakest of the three.
TAS/Mask of The Phantasm were glorious, but I do have to admit here my dudes that I was only really around for the end of the show. It started in September of 92, so I was 3 years old. I don't really remeber the show that well until the last couple of seasons.
New Adventures is a show I remeber fairly well, but even as a kid I knew that it looked worse than the original. Watched it, loved it, it was good enough for me.
The reason why I say beyond is better is purely nostalgia. Kids WB...Batman Beyond...Jackie Chan...X-Statix...Yugioh? Fuck. Yes. Batman Beyond was comfort food. I loved the setting, I loved the whole japanese neon sign vibe (I was getting heavy into anime at the time), and I thought Terry's GF was a total babe. I wanted to BE Terry McGinnis, and I enjoyed all the new takes on classic enemies. It just spoke to me, probably the same way that TAS spoke to some of you guys.
