Initial thoughts are that this should have been a 2 hour episode, not one. How did House end up in that place, no explanation. If the writers thought that wasn't the point of the episode, then they shouldn't have shown us that patient at all.
Didn't like the fact that it appears House had an epiphany following a meeting with a patient. He has derided other doctors when they did that, so couldn't find it believable that he would start. Unless he was looking for an excuse, but then it wasn't made clear enough to make it look like he was.
Did anyone else notice the absence of a former Dean of Medicine?
Given the last 2 or 3 episodes, the final few scenes seemed to give enough closure for that.
Given the how bad the past 4 seasons (from 5 onwards) have been, you couldn't have expected the final episode to be any better than this.
House started with a bang, season 2 was a frown, season 3 seemed to be back on form, season 4 short but sweet and exciting. Season 5 through to 7 was one long groan (with a few exceptions especially when Lucas was around - but the whole "Huddy" will-they-won't-they? thing was too drawn out and should have only last half a season). Season 8 was pretty much more of the same. And in the end it finally finished with a "meh"
