Other things about how good gargoyles is- notes on the animation.
The first five episodes have really crappy animation. The main human protaganist, Elisa Maza, looks like the little mermaid with black hair and a darker skin tone (and yes, despite my raving the series, it is perpetrated by Disney, blood, violence, and reality all). The color is weak, and lighting is generally piss poor. That gets progressively better as the series progresses however, up to the point where some bits of animation get absolutely gorgeous.
A personal favorite, two of the main characters are being hunted by a third (Marina Sirtis actually- this also happens to be ST:The Animated Generation, featuring Jonathan Frakes and Marina Sirtis as regulars, and occasional voice acting by Michael Dorn and Brent Spiner) gargoyle. They're in a cemetary, and they walk past an oakwoodish angel atop a pedastal, there's a flash of lightening, and just the wings of the third gargoyle are seen around the angel, as if the stone angel had opened its own wings. It looked really cool.
Another neat feature- the quality of the season can be determined by the number of episodes. The first season, overall good, with low points, was thirteen episodes. The second season, which fills in the holes of the first, was 26 episodes. The third season, which a few die hard fans, like myself, refuse to acknowledge as existing, was 8 episodes.
The third season is a real piss off. The second ends the show, pretty well. Main conflicts are resolved, it's vaguely open ended, a "new beginning"/"full circle" thing. And then they went a followed up this with a piss poor excuse for the series. I was upset.
