The first few seasons are fantastic! Great characters, great stories, great UST! However, I'm halfway through the most recent season and can't motivate myself to watch the rest :S They did something daft to one of the characters at the end of the last season (at least I think it was last season, might have been the one before :S) and the show hasn't been the same since. As my mum says "It's gotten silly and ridiculous", and seems to only be getting worse...
