i have see much bad but at least those movie have the gut to try something new ( even though they tank do it ) . the terror within be a rip off of alien . similarity include ( but be not limit to represent a homemade flamethrower and a chest bursting monster and lot of drool and a pair of engineer one black and one white and an age male captain who be somewhat heroic and a tense scene in something resemble air duct and creature reproduction include human and and a pet that be orphan when it owner be kill . the most obvious ripoff be the scene when they be search a storage room ( cargo bay ) for the creature . even the camera angle and shot order be similar to alien . i would like to give this movie a 2 but there be other movie i would give a two . and this isn not as bad a those .
