I went back and watched S5 of Doctor Who after I found out it was on Netflix streaming. I wasn't a big fan of that season when it first ran, but it's a lot better than I originally gave it credit for. Probably because knowing the ending it was a lot easier to see the foreshadowing and all the tiny details they threw in along the way, rather than forgetting about it in between weekly episodic airings.
I still hate River Song though. HATE. I get her as a concept, and I like the idea, but I swear to christ I want punch my screen every time she says 'spoilers'. I GET IT YOURE FROM THE FUTURE AND YOU CANT TALK ABOUT IT NOW SHUT UP.
