This is a pretty straightforward film without much in the way of surprises or strength of script or acting. The synopsis involves scientists working on some kind of chemical weapon for the UK government to use in a widespread revolt that has escalated into civil war which they are clearly losing. They somehow manage to get ahold of the leader of the revolution, Zakarian, and start using him as a test subject for their weapon.
the characters are roughly stereotypes, with Dr. Chrysler as the hard-ass with a traumatic past, Ruth as the New Girl with a conscience, and so on. Their interactions solely serve to mildly nudge at the theme of "we ams the real monsters" for doing human experimentation on a chemical weapon. They all know it, they acknowledge it, and it's never really a serious issue except for the purpose of cheap drama to further the plot along.
Without spoiling, the structure of the film seemed to hinge upon a twist ending that... largely fell flat. The film starts off with Dr. Chrysler in the white chamber, being tormented by Zakarian. This lasts all of about 15-20 minutes, before doing a flashback to 5 days earlier where we see Dr. Chrysler doing the tormenting on Zakarian. This takes up the majority of the film, and the odd structuring only seems to be in service of the slight twist at the end which could have been completely removed without affecting the plot in any real way.
This largely feels like a movie that had nothing to say and nothing to prove, no real reason to exist beyond providing work for the people involved. Everything came out adequate, competent, serviceable, and was left at that. Absolutely nothing stuck out in any way beyond the odd structuring of the film in service of a useless spoiler.
