* I really liked the way it was filmed, very crisp and clean.
* I really liked the villian. Her manicured nails and perfect little suit worked so well.
* Those were possibly the cutest aliens ever.
* The pantomiming was adorable.
* She brought baggage... and the Doctor was freaked, also mothers.
* Last but not least: Martha! She was really BRILLIANT and it was utterly and completely HIS FAULT.
In conclusion, once again they manage to do a really good character transition.
