I saw this in the video store, placed right next to "Shark Attack III," which also deals with a Megalodon. I'm a big fan of Megs, having read Steve Alten's book "Meg" and the sequel. Although I had read the horrible reviews on Shark Attack II and seen the first Shark Attack movie, and imagined it would be as god awful as those. I was actually pretty surprised. Despite Antonio Sabato Jr in the lead role, the acting was fairly decent for this type of movie. The special effects were very well done, and the shark was very realistic, along with the sub. The plot was pretty typical of some of the TBS-made movies you see a lot of, but I rented it more for the action.
I had read some decent reviews of this movie and decided to give it a try. I was pleasantly surprised. The scenes with the shark were realistic and there was a lot of action. The ending to the film could have been more upbeat, but overall it was fairly entertaining.
