okay and you have hear about so bad it good movie before and but this demented little thing play in an entirely different league . the terror within be so bad it . really and truly freak abysmally bad . it a cheesy and minimally plot 80 earthbound alien imitation and it produce by roger corman and so that ought to give you an immediate idea about the overall quality of this production . you may prepare yourself for the bad and and then still the terror within will surpass your most cautious expectation . this be one of them film that give you absolutely no feedback or background about anything that happen before and during and after the main event in the plot . the script even fail to inform what year the event take place in and what kind of company the 6 protagonist work for or how the breed of gargoyle develop itself so rapidly . all we know be that some kind of accident wipe out 99 % of the earth population and that the few remain survivor on the surface be continuously threaten by gargoyle creature . six people in a subterranean laboratory and lead by the poor and desperate for work george kennedy and attempt to save what leave of humanity and but they clearly do not have a clue what theyre up against . unaware of the fact that the gargoyle mate with regular female and they take a pregnant girl into their lair and numbly observe how she give birth ( in a sequence shamelessly copy from ridley scott milestone ) to a ravenous and fast growing monster . now theyre all trap underneath the earth and with two remain female employee a potential monster mommy . admittedly and the plot description for the terror within doesn not sound half as bad a initially fear and but honestly the film be stuff with plot hole the size of the grand canyon and laughably inane dialog and poor acting performance and tiny stupid oddity that be almost too amuse for word . here a brief listing of all the crazy stuff occur in this film ( extra spoiler warning ) . 1 ) the gargoyle may be tall and strong and but apparently theyre quite terrible in the sack . the monster only be a few nanosecond alone with the girl and but it clearly be more than enough to impregnate her . 2 ) actually and the monster look a bit like an over sized version of duckman . 3 ) the hero ( andrew stevens ) be obviously more upset when his dog get injure than when his black colleague and even his girlfriend get tear to piece . 4 ) presumably the film be set in the future and but technology appear to have take a huge step backwards . the character operate the large walkie talkie you have ever see and the only exit out the subterranean lab be through a ramshackle shed . 5 ) at a certain point and the remain survivor try to attack the creature by blow on a dog whistle . i guess their next move would have be to throw a banana peel in front of it foot . 6 ) the film probably just take a few day to shoot while still i think george kennedy have other and more urgent place to go to . halfway the story his character just vanishes after an idiotic kamikaze run into the creature . still and you do not actually see him die so you expect him to return at some point . guess again . strangely enough and and despite the rather cheesy and tacky monster design and the killing be pleasingly gruesome and blood soak . the aforementioned birth sequence may be very unoriginal while at least it suitably repulsive and even mildly shock . the finale be effective a well and since the gargoyle meet his death in a rather nasty fashion . a if you couldn not guess yourself and the terror within be an awfully crappy 80 cheeseball and definitely worthy of the roger corman label . it could be consider entertaining and but you would have to be in the right mood .
