I really enjoyed House from the beginning of the first series. However, I felt that it was beginning to drift a little recently. I mean every episode it would be that they'd constantly misdiagnose, just like they had in previous episodes. You'd expect lines like "it could be lupus" "no, it's never lupus" and so on. House and just about everyone else would psycho-aanlyse each other's motives for doing or saying anything. It had become predictable in spite of the ongoing sub-plots.
This episode, without giving anything away, is highly inventive, brilliantly scripted and has the hallmark humour that we expect. We get the series here in the UK some time after they are made (usually around a year) and I hope that we are going to see more great episodes this season. In any case this could just be the best House episode yet seen.
