Oh? My post from a few hours ago didn't post... Yeah, I was saying that I've seen the the odd few episodes, most recently the Season 4 Premiere - "Alone" - which I really enjoyed. I'll probably just watch Season 5 and follow the series from there on out.
I've come across quite a few of the spoilers about the season, but since I don't know any of the characters, excluding House, it doesn't mean much to me.
Also, by the time it starts, 80% of series are off air until fall. :/
