It's called Doctor Who. More specifically series five.
"The Eleventh Hour" was just so much fun to watch. The characters had great chemistry, and both Matt and Karen are adorable in a witty/lively/pretty way. The writing was fantastic and the whole episode was a great combination of old and new, perfect for a new Doctor and companion. The new TARDIS was amazing. I'm even convinced that the bow tie is appropriate.
This doesn't even include the mention of "timey wimey". That alone was win.
