I don't know what's up with all these people jumping onto the House bandwagon after one decent episode. "Wilson" and "Broken" were one time episodes that won't happen again. Obviously House is about House, not Wilson, and structure of a medical drama prevents House from being in a mental ward all the time. To say that "Wilson" is indicative of the whole show and puts trust back into David Shore and Katie Jacobs (whoever wrote that for the LA Times is being silly) is completely ridiculous. Looking at the season, there have been some very poor episodes and fewer decent ones. Why would one good episode change all of that?
There are a variety of factors that make an episode good, notably the concept itself. An episode using Wilson as the main character breaks the monotonous mold, and allows Robert Sean Leonard, a great actor, more screen time to shine. It's already a recipe for success. Some above average writing and the episode is set to make everyone go "wow!!!!!!"
The problem is that it was a very special episode that won't be happening anytime soon. Unless David Shore/Katie Jacobs decide to do several Wilson episodes per season, "Wilson" has no lasting effect on the show as a whole. The next episode will continue to have the annoying stories we've come to hate. Let's be realistic here, the same people were working on the show before "Wilson" and the same people are going to work on the show after "Wilson." There's no need to scream from the rooftops how great the show is.
Sorry if that was too long. I was reading some other reviews and comments, and got mad that people thought one episode instantly made the season great, and renewed their interest in the show. It would be like showing a smiling African and everyone forgets about Rwanda and Darfur.
I wasn't enthralled by the episode as everyone else was. It was nice to seen House diagnosing from another point of view -- the team rolling by was splendid -- but the Wilson story was about average. If it had been House diagnosing Tucker instead of Wilson, I think we really wouldn't have cared, especially without Cameron to narrate the sob story.
Wilson added almost everything to the episode. His interactions with patients are much more personal, and perhaps too personal. He ends up giving a lobe of his liver to his friend who turns out to be a douchebag. Surely House wouldn't have done that. But he did save a life, and House is still his friend.
