Just finished watching the entire series
I think most people up here have watched it. But if you haven't - watch it.
Even if you're not a sci fi fan (and I've never really been one), it's incredible.
Very clever writing, clever production, and when you least expect it, damn funny.
Was never a Star Trek fanatic, but am hooked on this. Even characters I initially didn't like (e.g. Donna), I wound up liking.
After the intensity at the end of the David Tenant run, I thought Matt Smith and the characters of Amy and Rory would be a big letdown. They weren't.
