except for the oddity of be take from three previous film and edit together all much old than the 1946 release date of this film and devil monster be one heck of a bad film with bad act and bad special effect and a terrible script and and virtually nothing go for it . a third be almost nothing but stock footage of seal and dolphin and and various tribe that look nothing alike in different scene . i be yawn after two minute of see seal wash up on rock and have inane dialog try and justify it presence . the original film could not have much good though because a couple of these actor okay and most of these actor be just downright awful from the lead barry norton to the excessiveness of jack del rio look like a psychopath at the ship steer wheel to the laughable persona of jack barty a the captain to the even more ludicrous native chief with a new york accent . only the fellow playing tiny the cook hold any of my interest and that really say just how bad this film be if you saw his performance . i really can not add much more to this then to say that the film be very and very bad and devoid of any merit whatsoever except if you enjoy watch people pour out their heart only end in cinematic misery for the viewer build by the foundation of their lack of talent and competence . sometimes i do . i do laugh several time at how bad really bad thing be .
