Honestly, while Moffat's "emotional" stuff has been pretty garbage in the Capaldi era (mostly because 90% of "emotional" stuff were horrible Clara scenes), I think he did a decent job in the 11th Doctor's run. A Christmas Carol still gets me everytime I watch it, and Time and the Doctor (despite its flaws) had a great, and emotional, goodbye to the 11th Doctor. I think moffat can do emotion well, but I'd definitely want less stuff like that in Season 10. I cared so little about the "emotional" Clara stuff that I just want Series 10 to be a big adventure, without any heavy "relationship" stuff.
