This one is sooooo stupid - like an e-mail spammer offering you "fantastic job" carrying manure in supremely orban Back Water Oklahoma, last post office Lower Wasteland.Thank God for fast forward, but even that didn't help. Whoever paid for this pile of gosa needs to get a life sentence for crimes against humanity. Not kidding at all. This was colossal insult not just for the genre but for the cinematography as a notion and the hard drive space wasted to hold their "material".There needs to be a warning flag on IMDb to let people know what to skip.

This movie is a circle of nothingness that ends well thought an ending!! DO NOT WATCH!! Creepy and the movie ends without an ending. POINTLESS!!! Worst movie ever!

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.

Again, and again, and again, and again... they keep making movies about trillion dollar, extremely important space missions and then "they" assemble a crew that consists of people that can't get along, panic about basically anything and don't know how to follow orders. The crew in "400 days" is no different. No single space agency on this planet would EVER put these people together in a confined space. For the rest of the movie... read the other reviews. I'm just sorry for wasting another 90 minutes of my life on this junk...
