The House M.D. season finale was good. The two-parter was good. The whole season was good. By which I mean, "I was taken on an emotional ride and given vicarious sensations that made me forget my own mortality." Highly recommended. Even if you don't believe in catharsis.
Two comments on long-term story construction things:
Everybody lies. => Everybody dies.
You can't always get what you want: reprising the pilot.
And the José González acoustic cover of "Teardrop". Excellent.
