This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

While it doesn't offer any answers, it both thrills and makes you think.

The acting in this movie is really good.

The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

The astronauts Theo (Brandon Routh), Emily (Caity Lotz), Dvorak (Dane Cook) and Bug (Ben Feldman) are locked in an underground facility imitating a spaceship for 400 days simulating the travel to a distant planet. The intent is to study the psychological effect caused by the long isolation period without contact or communication with the outside world. They experience hallucinations and weird noises on the outside and close to the day 400, they see a stranger in their ship. When the man flees, Theo and Bug leave the facility and they find outside world dusty, dark and desolate. They decide to walk to seek somebody and while Dvorak believes it is part of the experiment, Theo, Emily and Bug believe that something bad may happen on Earth. "400 Days" is an intriguing thriller with an absolutely frustrating conclusion. There are flaws in the story (how a weak man like Bug is selected for such experience is probably the worst) but in general the film builds the mystery with an increasing tension. Unfortunately the lack of conclusion is a cold shower in the viewer. My vote is five.Title (Brazil): "Protegido: 400 Dias" ("Protected: 400 Days")

First off from the get go this movie has a awful script awful acting and just a straight up awful story line to it. The only reason I watched it was for Dane Cook, and his character (Dvorak) sucked! You're left with so many lose ends it's mind blowing. What the heck happens to Bug and Dvorak??? And why does it end with just light coming down the hatch??? You're left with way to many in answered questions. Do not give this movie the light of day.

Four astronauts, 3 guys and a girl get locked up underground in a simulator for 400 days. We get to watch them build character for half the film. There are issues with low oxygen that cause hallucinations which we get to see. Then the simulator shakes and loses partial power. Is it real or a simulator test? Did something happen to the Earth?This was a SyFy film that attempts to be a Twilight Zone episode. Apart from the fact the astronauts were boring, dialogue was bad and the ending had no closure, it was so-so film. 2 1/2 starsGuide: No sex or nudity. F-word. My advice watch "Air" instead or binge watch the Zone or "The Outer Limits."

I was willing to put up with 89 minutes of the low-budget quality of this 'film' just so I could see what apocalyptic calamity had befallen the earth during the crew's 400 days. In the last minute the director and the rest of the incompetents implicated in this pathetic attempt at storytelling just gave up and left the viewer with a whole lot of nothing when we would have taken almost anything. Nothing endings only work well if crafted by skilled storytellers. Inception had a great nothing ending. For his sake, I hope this director just ran out of money – at least that would be a reason which would compute. You're not being 'cool' 'edgy' or 'neat' by ending it this way. Netflix even got in on the scam by claiming in the description that the crew weren't sure if the 400 day test might actually be real. This was never the illusion they were dealing with. Anyway, I guess I'm the fool for not checking here for reviews first. Fooled me once...
