I actually find this film entertaining as a b-movie schlock horror, rather than a tense thriller that was the original. Just to remind people about the effects: yes they are shoddy, but then again the shark in the original is unconvincing too (when it appears). This film was shown at cinemas as 'Jaws 3D' and was supposed to be viewed with those red/green spectacles, hence the rather perplexing scenes such as the fish head or when jaws smashes into the control centre.
If you view it as a horror fan, there are some great death scenes; the shark is really quite ominous due to its ridiculous proportions and there is great shock value at some of the grisly deaths meted out to unwary divers. Best/worst death is Simon MacKorkindale's (Holby city/casualty) character's ( you just know that the English guy is going to die in the most horrible way!) : he is attempting to lure jaws into a vent to trap her (she's a mother, after all) but his life-line snaps and he gets trapped in the vent with her...he then somehow ends up (still alive) inside her over-sized mouth. You then hear his bones cracking!! Truly disturbing, even if it's totally absurd as well!
Don't know if I'd buy it, perhaps best to watch it on channel 5 ha ha!
