That is where I disagree
I like gimmick episodes, but too many of them can ruin the season. I like Angel better than Buffy because of the overall storyarcs, which are better on Angel. Plus, gimmick episodes don't always add to the season's story.
Riley hunts vampires, Buffy hunts vampires. There going to run into eachother.
Oh wait they did, in season 4, 3 years after Buffy started slaying in Sunnydale. Why didn't they run into each other before hand?
