IT was great, but they pounded the living hell out of the "he can't be right, he's on drugs"
or "he can't be right, because he hasn't got morals and he doesn't care"
or "he can't be right, because I don't want to be house"
or "he can't be right, because he was wrong, once, when we forced him to go off drugs"
Meh, it got old quickly and I can't stand Foreman, and his character makes no sense, basically every important time, he's been wrong, every single time, he's killed people, he's got the angry thing, he's always wrong, he's stuck up, he constantly bangs on about not being like House, despite being a much worse person, as an actor he constantly does the cringe "angry face", to show anger, happyness, hornyness, love, sadness, etc, etc.
As a doctor he should have been fired so long ago its a joke, yet they keep putting him in charge, and taking it away and rehiring him and firing him and giving him a team and then taking it away.
Thats mostly why series 4/5 was crap, Foreman out of the show years ago would have made everything much better.
Also though they've writen him coming off the drugs very well in series 6, its because apparently the drug enforcement agency said they really didn't like a doctor being soo good while on drugs as its a bad message, so they had him flip out on drugs then get better when off them.
