I'd heard about Pet Shop of Horrors a number of times, and people seemed to be fond of it; last night I finally got around to watching it.
The older animation didn't bother me. The concept, while somewhat strange, didn't bother me. But the show itself was a let down. I'm not a big fan of the horror genre, not because I don't like a good scary movie, but because so many of them are focused too hard on the situtation itself, rather than the characters.
I cut off after episode one. Given the concept of the show, I couldn't see the formula changing from what it was in the first episode: Count D sells someone a pet, and they do exactly what they're told not to, then they scream as things go wrong, and Count D comes back at the end. Blah. And top it off with cardboard-characters.
I believe horror should be focused on the characters, the horror should be that of the person the story is about. But unfortunately, most horror creators seem to be far too interested in the "scary situation" they're setting up. But perhaps that's just me.
