I definitely agree with your reaction. I was left feeling quite underwhelmed. The episode reminded me of so much I hate about Moffat's writing and his overly complicated plots and story arcs. And it just did not have the emotional effect I was hoping for. I wasn't very happy with The End Of Time either, but I connected with it and felt so much when it was Ten's time to go. With Eleven's regeneration, it was more my sadness for wonderful Matt than anything else. For me, nothing can compare with the wonderful Parting Of The Ways.

And, needless to say, I am so very bitter Moffat couldn't be gone together with Eleven...
