Fantastic watch, will watch again, and can recommend if you're okay with on screen death and philosophical debate or game theory.
(Think "Saw 2" with no gore.)

It is always impressive when someone creates a good movie that occurs in a single location.

Under the premise of alleged aliens abducting group of people forced to play a death game, we get to see what humans intend to do without authority in a structured environment. This movie is very "Twilight Zone".

It's hard to cast for 50 "leads", and the "leads" kind of shift and rotate about during the game as people become targeted, but most of the actors in the game give a serviceable delivery in their roles, and while the production value is definitely there, you can tell that there just wasn't much necessary past the set and the kill mechanism. Hell, this looks so affordable, you could probably turn it into a regular show: there are party games with similar concepts.

There isn't much to say without spoiling other than this is a lot of talking: literally discussing who should live and who should die.

While I find such things fascinating, other people may want to watch romance or explosions, and there are plenty of those movies out there too.
