shiver ( aka they come from within ) be another pretty twist out from freak o canadian director david cronenburg . shiver be not nearly as memorable a some of cronenburg other work ( videodrome and the fly or my personal favorite the brood . ) but it be still worth a look for anyone that be into cronenburg strange cinema . shiver be about parasite that enter their human host and cause them to do all kind of strange sexual and violent thing . pretty cool concept that be handle well and and the film be both weird and entertain a only cronenburg can do it . again and not the best of his film by any mean and but still solid . give it a shot 7 . 5/10 .
