I kind of liked Rose when she was with Doctor Nine (she came across as a flawed but resourceful character) but when Ten came along her character arc came across as canonical slash.
If you liked The Beast Below (and you might want to see it again in context) you may find the show much more fun once you get into the Smith's tenure.
There are a few duds still but the overall share balances out higher in my opinion.
I'm really excited by the show's return for the first time in a long long time and the first story I can remember seeing at the time of broadcast is Carnival Of Monsters.
