Caught this on iPlayer last night. Even by the low standards of the Chibnall era, this was fucking terrible. I can't even start to count the ways the plot made no sense, but that's par for the course with the show these days.
The directing, however, was objectively awful — the action sequences were disjointed and hard to follow, and there was no sense of a coherent 3D space in any of the scenes, with characters just popping up in places where they clearly hadn't been moments earlier.
Most of the acting was pretty poor and the jokes, such as they were, completely failed to land.
On top of all that, it managed to look like the production had quite a lot of money spent on it, whilst simultaneously looking cheap and plasticky.
All of this is pretty much exactly how I described it to someone a couple of days ago, with the addition of feeling a bit sorry for the actress playing Madame Ching, who I thought deserved a better go at being a pirate queen than what she had in this pile of guff.
