be it a coincidence that orca be make two year after jaw . orca isn not exactly a jaw rip off but it be obvious that it try to profit from jaws success . first of all orca in my opinion be a bad movie and not terrible but definitely not good and average at best . the plot be basically a male killer whale ( orca ) after see it mate and it unborn calf kill by a fisherman seek revenge . i couldn not stand to watch this movie again . the direction of this film be poor and when compare to jaw it look like the director and producer and and writer be almost talentless . a for the acting and it be very average and believable and however the actual character aren not the least bit likable . the effect be alright for it time and the footage of the killer whale look pretty good . the violence be confuse and bloody and and not recommend for more sensitive people . the music be overdone and very loud and drown out the sound effect and irritate at time . i hat the way they exaggerate the intelligence of the killer whale ( killer whale do not mate with only one mate a depict in orca ) . overall this movie be bad or poor in my opinion and because of the reason list above . some people may appreciate this film more because of the concept of vengeance amongst animal and human so i be not go to bash this movie and i can understand why some people may like it . my rating represent 3 . 5/10 ( but for it concept possibly a 5/10 ) .
