Considering how repetitive the main formula is, you'd think the show would've grown really old by now, but the fact that it hasn't deteriorated that much says a lot. And yes Taub's storyline is weak but watching the rest of the team make fun of him always cracks me up.
The thing about House is... it shamelessly follows that formula because it simply has the writing to keep it fresh and entertaining. We know how the story goes... the patient comes in, they debate it.. think they have solved it... shit hits the fan... then House has an epiphany. But the patients serve as a catalyst for getting the rest of the cast to interact in certain ways and discuss certain themes. Really the patient itself isn't very important... it's how they effect the rest of the cast.
Really love this show.
