I dont watch Who much, but watched this and the last ones and I have to say this one was pretty "meh". The last one wasnt the greatest either, but it was a lot more enjoyable for me being that I liked Tennant.
My biggest issue with Smiths run wasnt that I disliked him or Pond, in fact I really liked them, it was that I never liked the writing beyond a few episodes here and there.
This tie up episode (that proved I was right about the regenerations) felt like such a cop out, especially the Time Lords decision at the end.

There were some nice touches though, such as the hologram that only Clara could see, that genuinely made me laugh. But overall it felt somewhat forced and cheesey even for Who.
