The was a similar movie about a shark made back in the 1950s, but don’t let that put you off. This is better in every way. In this movie the shark swims through sand, not in the water, which is a really great twist because no one expects it. Also the shark in the first movie was obviously just a cartoon fish someone drew, it was a totally cheesy movie and badly directed. This one is modern and the music is louder, and uses a real trained sand shark. Those actors are really brave, apparently one of them nearly died so you should see it for them. Wow.
