The kids will be bored, the monster was silly (if well-rendered) and it felt a bit too message-heavy in places (especially Bill Nighy's speech about Van Gogh's place in the history of art, and with the post-show ad for an advice line) but....
Easily the best episode of the season, and best "celebrity historical" of Nu Who. Mainly because of a) Curtis' script having a mix of a good grasp of the subjects and some lines that play differently depending on whether the viewer is following the arc, and b) Tony Curran as Van Gogh, who was bloody amazing (couldn't we keep him? Or at least cast him in a "proper" biopic about Vincent?)
I suspect it won't win any season polls, but fuck it, no, this was *quality* even when it was being just Dr Who with a monster.
