Aquaman. I had lots of negative things to say about this film when I saw it in the cinema, but a home viewing proved me wrong: it's really very good fun, and the level of visual invention is impressive.
Originally I was put off by the last half hour, which just throws one thing after another at you (the Trench, the Hidden Sea, the kaiju-thing, the Brine..), but being aware of how it all fits together the spectacle is a lot more enjoyable. To my chagrin an early bit of exposition sets all this out quiteam clearly, but it went completely over my head first time out.
Lots of silliness, but no worse for it.
