You see the rating. You know the show is good and you liked it so far. You want and end fitting to House. And it is. It fills the character's development to a twist that will finally give the character rest (no spoilers intended in that sentence, just trying to say it will give the character a means to an end for his development and the show's end will make sense for everyone).
Now this is for the negative reviews this episode has, despite the overall high rating. Let me explain why that is: People want a grandiose finale of epic proportions that could fill stories for centuries to come. They want an epic prose that will be grandiose on every scale and they get disappointed when they get a twist that is something much more real and heartfelt than that. House's ending is for the thinking mind of the viewer and the thinking mind of the character. It brings them both peace of mind. People expect either a epic victory or a really sad tragedy, and when they get neither and instead get something entirely different (and ingenious), they don't understand why it is like it is and complain. It's like they didn't watch 8 seasons before. It's like the missed the entire being of existence that is House. So please do not listen to those people. They have an incompletely developed emotional intelligence, they are still stuck in the middle of their intellectual growth and therefore cannot accept an end like that one. It looks as if it is too small of a stage, when it's actually as large as life itself.
Please watch the show.
