@Sylvhem mostly I'm just tired of moffat, I'm looking forward to what someone else can do with it

Just lots of little things, eg. the doctor does a grandiose speech, those can be good, but not when they're used to tell not show, like the doctor explaining how he reprogrammed the cybermen. And scenes that were drawn out or had the pacing wrong (bill not realising she was cyberman, but she looked in a mirror straight away)

and the ending annoyed me, because I wanted to like that heather showed up - I was cheering - but then she did a bunch of stuff that hadn't been previously established she could do, and it just became a big deus ex machina
