One of the huge problems with this whole era is that there's just no link between it and previous eras, or even between Jodie and previous Doctors. Of course it's a reboot of sorts, but some things need to stay the same, at least at the start. Tennant had Rose and the production as a whole so that was fine.
Moffat almost killed himself with introducing Smith, 2 companions and the coming of a whole new era with the 11th Hour, but even then he still had little links like Murray Gold and the general structure of his first season (Plus the fact he had written some of if not the best episodes of NeWho up to that point). Then with Capaldi he had both Clara and previous characters he had created to work with, plus a lot less to have to actually do (Only really introduce a new Doctor).
CC however tried to introduce a new female Doctor, 3 companions, whilst his work on the show having been average (At best) before. That plus the fact that there were no real links at all in terms of writing, production or seasonal structure, as well as no stand out performers (Like Moffat was during the RTD era) the whole thing just comes across as bland and alien. I mean, it's not exactly totally terrible but it's just sorta there, and wether it's good or bad Who should never just be 'there'.
