When you think about why a fourth movie was made, Michael Caine summed it up best. When asked why he was in such a horrid movie he answered "Because they're paying for my drinking habit". And considering he couldn't accept his Academy Award for Hannah and her Sisters because he was filming this movie, you can understand the bored look on his face throughout the movie.

Years after the horrors on Amity Island, Ellen Brody seems to have settled into life again after the passing of her husband. When her youngest son is killed by a shark on the shores of Marthas Vineyard, she leaves to visit her other son Mike (Lance Guest) in the Bahamas. But this movie is about revenge, so the shark follows her to warmer waters, meanwhile she's fallen in love with a local pilot (Michael Caine) who's not in favour with her son.

Bad shark animatronics, bad acting, bad sets, bad scripting and bad execution make for a, you guessed it, bad movie.

It bites.

Visually, this image is a much better effort than the previous two with a cleaner 'newer' print, decent black levels, high sharpness and detail and some rich colors. DVD has an uncanny knack of making effects look a little too obvious such as the 'backdrop' in the final sequence where the 'heroes' are in the water and original footage of the shark from Jaws is reused. Talk about budget constraints that would make it obvious this movie should NOT have been made.

Sound wise, there is no real improvement over the previous efforts other than the use of the original classic theme throughout. But when you start hearing a shark roar, and even see it stand on its tail, you really do have to wonder just how far fetched everything about the movie can be.

Extras are the standard fair for the last two sequels, with trailers for all three sequels.
