The Eleventh Hour
First two minutes:
I don't like him. He's not my Doctor. WHAT HAVE YOU DONE WITH TENNANT! BRING HIM BAAAACK TO ME!!!
Four minutes later:
OMG I love him. He's amazing. He's just chucking food everywhere and munching on fish custard and being all lovely. What was I even talking about before? I don't even know. I don't care. Matt Smith is just- I CAN'T!
