Batman: The Animated Series (hereafter known as BTAS) is a very good show, and is, for my money, the best non-comic book version of Batman. Screw Christopher Nolan, and his whiney-bitch characters, screw Christian Bale, with his ridiculous Bat-voice and tedious acting style. Screw Tim Burton's total inability to tell a story, screw Joel Schumacher's terribleness, screw the jokiness of Adam West or Batman: Brave and the Bold. BTAS is the shit. I mean, it introduced Harley Quinn into the world, and indirectly lead to Paul Dini's excellent run on the Batman Dective Comics line (as well as the upcoming Zatanna comic holy shit Paul Dini is writing a Zatanna comic that is going to be so awesome holy shit holy shit holy shit), but apart from that, it is just very good at telling very good stories.
With that in mind, Cat Scratch Fever is not a great episode. It certainly wasn't a bad episode, but it wasn't great. The villain was kind of boring, and his henchpeople were pretty annoying. But I did like the fact that they put Catwoman on the path towards being a kind-of-hero at this point, which is something that does pay off later with some better episodes than this one. And I did like the fact that she started the adventure as Selina Kyle, in hopes of leading a normal life, but her love of cats forced her to take action. It was only after she had failed to stop the bad guys as Selina that she turned in to Catwoman. I also really liked the ending, where Batman gave Selina her cat back. No dialogue, no meaningful glances, no nothing. They didn't even have to look at each other. It was so goddamn romantic and sweet. Batman - secretly he's just a big teddy bear, and that's how I like it.
NOTE: I do actually like The Dark Knight, Tim Burton's Batman, Batman Returns, Batman: The Brave and the Bold, and the Adam West show. I just think BTAS is better.
Batman Begins is rubbish though - Scarecrow is such a stupid fucking badguy.
