Peter is waaaay too overpowered and so is sylar for that matter. Honestly I think they should have killed each other in season one then we wouldn't have this escalation problem. To be honest I hate Peter Petrelli my extreme dislike of him stopped me really watching season 2 and I haven't even bothered paying much attention to season 3. And dammit did they make Mohinder more dark/evil? He was one of my favourite characters, why can't they let me remember him as he was?
