this film be make before the day of cgi and therefore must seem painfully date to young viewer but to u who grow up in the atomic monster age it be both scary and charm . we do not look with judgment on the film but rather on the time in which it be produce . fond memory of drive in theater and saturday night scarfests with friend . carefree time of youth and adolescence . that say behemoth be ultimately more entertaining with it challenge fx than many of our modern day film which completely lack any charm . simply fill a film with eye catch cgi do not a movie make . willis obrian painstaking stop motion effect and eugene lourie talent with a minuscule budget unite to make a scary premise very entertaining and certainly fondly remember .
