American remake of the German movie "Das Experiment", which is based on the Stanford prison experiment that actually truly happened at the USA.
This movie is bad, extremely bad, to the point even that I have actually chosen to give this plainly the lowest score possible.
The fact behind this is that it is based on a real story, but as it only has a short time to show it, parts are omitted, changed, and in turn there are too many flaws in the storyline to make it a convinceable movie, like the fact that no violence was allowed, yet nothing happened when violence happened, not even when one got killed, and there's no reference at the end of the movie about it.
In all honesty, it all feels sloppy, put together in a whim, and forgotten to actually make it complete.
The only thing I could say is that the acting was sublime...

Still, on more of a side note: possibly I am biased when it comes to this, as I do know the story behind the Stanford prison experiment, and I am someone who doesn't see it in any way as a positive thing, and I see the one behind it, Philip Zimbardo, as a criminal and a lunatic. Let's not forget that the experiment was technically based on Nazism...
Apart of that, it hasn't caused any factual benefit, as do not forget about what happened at Abu Ghraib by the American Army...

Anyhow, possibly the movie "The Stanford Prison Experiment (2015)" is better, I do not know, I haven't watched it.
But regardless, I would advice to skip this one, as it is quite likely to leave you with more questions than answers, and not bringing across the full message...
