The animation is terrifying, the Shalka were sadly not that cool, the screaming got old very fast.

But the rest is 10/10!!!! Richard E. Grant's Doctor is as good as they say. Really feels like a mix between Eight and Nine, amazingly. Maybe a bit of Twelve as well? Allison, the companion, is also very nice, dumps her boring boyfriend to go travel with the Doctor, as she should. But the android Master the Doctor just has hanging around in the TARDIS??? Android Master that the Doctor built??? Amazing. Congrats on the wedding. Very Twelve/Missy coded. No further comments.
