As a whole, I really liked DW season 10. I'm wasn't a big fan of season 8 and 9 (even if I really liked some episodes, like Heaven Sent) but I feel that season 10 was way better.
I especially loved the Bill-Nardole-Doctor trio. The chemistry was pretty good between them, and it made some episode really epic (especially when we had the "fourth member" of the team :p).
I'm really interested with what the new writer will do with the serie, now that Moffat will leave with the Christmas episode.
