3 star is ok...since it was entertaining more than suspense....like the character kept changing within themselves. 20 min u will see Howard apologetic..Next 20 min u will see him goin crazy criminal...like Killing emmer over a gun issue...like gimme a break why the hell did u help him at first place ....and if u made ur mind to kill him.. do it straight why confess him and shoot...lead role actress was fully charged up for last 10 min..like had 10 extra red bull from bunker....moral of the story if both knew that Howard was coward..2 could have easily taken on one..and happily lived after in bunker ....why did they never heard extraterrestrial activity before she comes out..loophole all over
