I thought it was Ok personally, not brilliant, but not terrible either. The only things which got on my nerves were:-
A) the robots... their voices were just irritating, their banter (both between themselves and other characters) and so on.
B) Just the general idea of dinosaurs in space... it just seems... silly... to me, but not un-watchable, it did seem quite well executed even though I wasn't initially keen on it.
C) The ending where Nefertiti shacks up with that random hunter guy.
Other than that I still thought it was decent.
but....I still think they have become worse as Moffat has gone on with them. He makes them confusing (last series case in point, it was confusing to watch the story unfold, and when it was finally revealed and I understood it, it didn't seem that great anyway...), and generally I find some of the more... wishy-washy/mushy stuff more irritating than enjoyable (case in point 2: Craig blows up the cyber-men with love, and all the stuff surrounding River song marrying the doctor... my memory is a little hazy on the episode but did they really have to do the whole ****ty wedding scene? All I remember watching it was that I had an over-whelming sense to claw my eyes out...). I suppose I'm looking for a more serious Dr Who than what's currently available... shame the last Torchwood was an abortion of a series.
