Ever since the Season 3 finale, the show has been a mixed bag. The thing last season is that there was too much characters..uninteresting ones at that. They tried to keep the show fresh by sidelining part of the original cast and brining in new faces. It might have work and simply hasn`t. The new characters are copycat of the old ones and the most annoying thing is that the writers keep on trying to force them onto the audience. But there is the no dynamic as before and the best episode of centered on the original cast. Kutner is meh, Todd`s problems a waste of screen time and 13 being a lesbia scenes are hot but she remains forced, boring and a bad copy of Cameron. Add to that, we get very little of Chase and Cameron usually and Foreman is in the background (remember the Foreman centric episode in the season 1? That was quality). It is the wrong formula. There were uninteresting cases in the earlier seasons as well but covered up by good characters, now any centric about the new characters is bound to failure.
NOW that the rant is over, onto the episode. 3 episodes stands out so far for this season:Birthmarks, Joy and this one. All have one thing in common: they center on the original cast, there you have it. This is the first episode in a long time we`ve had so much of Chase and Cameron. Meanwhile the thing going on between House and Cuddy with Wilson in the middle is ever interesting and entertaining. No 13 dying, no forcing of flat characters, that right here is the right formula for this show. House is awesome, Cuddy, Wilson, Chase, Foreman, Cameron and even the detective guy is great...the others ruin the show, it`s as simple as that.
