This movie is truly bonkers. I don't really know how Hyams sold the concept of this to the studio execbots: "yeah, Universal Soldier 4 is going to be a pastiche of loads of common sci-fi tropes -- like clones, body regeneration, implanted memories -- that I'm going to mix in with Kubrickian slomo camera shots, Lynchian psychodrama, and loads of Apocalypse Now. We'll have Van Damme ape Brando's Kurtz and have him walk around a lot mumbling and looking miserable, and not fighting, and Scott Adkins driving around a lot looking miserable, and not fighting, and some random big dude with a beard who fights everything. But when it gets violent I'm going to push the violence as far as I can, and try and offend everyone with my opening sequence. It'll be great, I'm telling ya."
In all seriousness, this is not a movie for everyone, but I quite frankly loved it. Hyams really does let his imagination run wild on this one, and cheerfully cribs from loads of other directors and movies, but he never seemed to get the memo that this is the fourth in a series of increasingly minor action roles that no one -- save for the odd action junkie fondly remembering movies from his or her childhood/youth -- cares about any more, and tries hard to make this movie anything but your conventional DTV B-movie with ageing action stars.
Day of reckoning is crass, extremely violent, uneven, and low budget, but it should also be commended for being ambitious, and shot through with passion and creative vision. It is absolutely not a movie for everyone -- if you want a safer trip up action-memory-lane stick with The Expendables 2
-- but if you fancy a detour of the beaten path, and are willing to forgive the flaws the flaws that are a consequence of the directorial ambition, then by all means give this a shot.
Just remember that the film is absolutely bonkers.
