maybe the core concept but obvious the methods and consequences were different. although the Doctor did say that Donna was special enough to warrant a new universe but most people were just adjusted for (like in Blink).
though the more I think about it, the more I wonder. the Doctor mentioned the library which was a Moffet script, and he tied this story to that one.
I do think this series is my least favorite. No matter how good the finale turns out to be, the series as a whole has not been as good as prior years. The Doctor-light episodes are normally among my favorites (Love and Monsters, Blink).
I like Davies but it's time for him to go and for Moffet to take over.

Bow ties are coool.
