6 Underground is the most Michael Bay film ever conceived. Structurally, it's a mess and the humour has his trademark mean spiritedness all over it. However, that also means it's a gorgeously mounted globe trotting adventure through some top tier Bayos in which anything that can blow up will blow up.

Ryan Reynolds isn't really pushing himself here and it would be stretching it to call One a character. In Bay's hands though, he's dialled up to eleven in a way that matches and controls the film's manic energy. He pretty much shouts every line which wouldn't work in any other film but is ideal for this one.

The rest of the cast are all really good at complaining their way through the film. Mélanie Laurent is the coolest, Manuel Garcia-Rulfo is the funniest and Corey Hawkins comes closest to having an actual character. He's the only one able to briefly ground the proceedings when necessary.

Whatever problems the film has with its narrative and structure, Michael Bay's technical craft remains unrivalled. Retaining the scale of a Transformers whilst returning to his R rated roots, the carnage on display here is pure art, ageing like a fine wine since it's now one of a few Netflix blockbusters that looks like an actual movie.

Lorne Balfe truly understands the assignment with a score that's low on subtlety and high on bombast. It can make even the most thinly written character beat feel like it has some genuine weight behind it and if that doesn't work the soundtrack is always on standby, ready to go with something that will really seal the deal.
