Definitely enjoyed it!

The song was a bit shocking, but fun. The Doctor singing wasn't all that crazy, but Ruby doing it was. Hopefully they continue to show her being that quick witted in the future.

I'm not sure on the new sonic though. When I initially saw pics of it, I thought it'd be a bracelet type situation and that's cool, but that doesn't seem like it's the case and it just seems big and bulky. Time will tell.
