Catherine Tate was actually not that annoining. It's just that you can't help but notice some of her characters from her comedy show peeking through into her acting. You do expect her to say something like "what a f**king liberty" or what not, but on the whole she was ok, not half as bad as the Christmas special a few years back.
The little 'fat' monsters were just to cute, and the villain wasn't really that, but being the season opener it really was just a case of bringing the Dr and Donna together again.
There was a nice surprise at the end though, which I won't give away.
An ok-ish episode, but not the Wow we were led to believe with all the hype and interviews we had in the last week.
Next week the Rome episode.
