Saw this last night. 10/10 for concept, but 7/10 for execution. I liked this movie a lot overall and it definitely blew my mind, but just feel Garland's execution could've been better on this.
The first thing I'd say is that this is one heck of a trippy movie and so far "out there" it's the kind of movie that I bet even most indie studios probably would never want to release. Heck I'm having a hard time believing that even A24 released this. I've seen a LOT of artistically crazy movies but Men might take the cake as being in the top 5 of that list easily. And if there was ever an anti-crowd-pleasing movie that would either upset or confuse the audience, Men would definitely be near the top of that list as well.
I definitely see Men as Garland's further progression of venturing less from sci-fi and more towards allegorical surrealism (and the fantastical), as he kinda started to in Annihilation. At this point I think it's safe to say that Garland could probably work on being more subtle about his allegorical subtext, because some of it was just way too on-the-nose, but at least I appreciated what he went for here (although with basically the subtlety of a jackhammer at certain points).
The acting performances were definitely strong, but I honestly was more impressed here by Rory Kinnear than Jessie Buckley. But by far the strongest part of the film was Garland's directing - he clearly has an extremely unique artistic vision in his movies, he's not afraid to show it, and it shows SO MUCH (which was the aspect I loved the most about this film).
Forewarning: the film has quite a bit of male nudity and some very bloody scenes (but none that are really "gory" per se).
