I got into the show rather recently, around a year ago, and started with the new stuff.
SPOILERS FOLLOW THIS LINE IF YOU HAVE NOT WATCHED IT AND DO NOT WANT SPOILERS ABANDON READING HERE.
So, I thought this season really lacked "cohesion" in some of the episodes. In particular, The God Complex (the one in the creepy hotel/prison). Also, I felt it was missing that "epic" feeling some of the other seasons brought.
Otherwise, it was a very good season with a very clever, if predictable, ending.
I think if you didn't see the fake death stunt with the Tesselator coming I think you need a new show to watch.
I still really miss Rose though, she was far and away my favorite "companion"
Anyway, just wanted to spill something about it because I just watched it and my girlfriend doesn't like Doctor Who so she won't listen to me talk about it.
