this film have me seriously doubt again whether armando de ossorio be a good filmmaker or not . his blind dead film be praise by many fan . this i can understand . but wan na be gothic vampire trite like malenka doesn not show any sign from a gifted filmmaker . and that also go for serpiente de mar . it feature horrible acting and a dumb plot and stupid event and a lot of other thing you can expect from a bad monster movie and also veteran actor ray milland and who do his best to mumble his way through this film while not have much of a clue about what he do in it . apparently milland be already very ill while shoot serpiente de mar ( his last theatrical feature ) and go out with a ridiculous stinker like this and make it all the more sad . one last appearance alongside peter cushing in a make for tv film direct by roy ward baker ( also in 1984 ) doesn not change much about it . but the sock puppet or sea serpent be a hoot to behold . watch it swirl up a lighthouse and crush it . see it destroy a harbour with miniature boat . look at it demolish bridge and munch on charm miniature train . good badness . yes . negative and positive .
