I don't want to get too specific on plot lines because I don't want to spoil the season for you, but keep watching. For starters, Spike is freaking fantastic. And don't worry, the climax of S2 is probably the best of any T.V. series I've ever watched, and once it happens, trust me, you won't even remember the Anointed One.
But as for the kid himself, I thought he was alright. I didn't really think he was anything special, but I thought the actor who played him did a good job. He had that creepy feel down pat. I was a thrown when he fries though. I mean, they had built him up as this major player throughout most of S1, and then...nothing. I've always kind of wondered why that happened. My guess is either fan reaction to him was poor or the kid himself was getting too old to play the part (wouldn't be the first time that's happened).
Either way, I wasn't broken up when he died. And I have to say, I loved his death. Spike owns that episode, at his finished it perfectly 🙂.
