Query: Pretty good Who

Great example of the Doctor's intellect triumphing over brute force and evil conquering aliens! Lots of interesting twists to maintain the viewer on the edge of their seat.I found the ending a bit un-Whovian, as the Doctor isn't normally one to ignore loose ends, especially when someone is in need. That's the only reason this gets 4 stars versus 5.Great season opener! Can't wait to see more!
