It was real surprising for me to find out how watchable this movie actually was. I mean, a movie in which a shark attacks a bunch of people trapped in a supermarket, after a tsunami hit, doesn't exactly sound like high quality stuff. As a matter of fact. you would normally expect a movie like this to be extremely bad and cheesy but the movie, as it turned out, was far from cheesy and simply was being pretty good for what it was.
I still expected the worst, after the first 15 minutes or so, which wasn't exactly being a very promising start for the movie. It looked horrible and I feared for the rest of the movie. I expected it to be a very formulaic genre flick, in which nothing exciting or original ever happened. And even while the movie isn't being all that original, it still feels like a good watch, since it manages to entertain and takes itself serious enough.
That was perhaps being the key as to why the movie worked out; it took itself serious. Normally modern B-movies are very self aware and actors and directors obviously don't take their work all that serious. They make things deliberately cheesy to add to the fun factor and while this does work out at times, at others it makes the movie noting less but bad and annoying. In that regard it also was being refreshing to see how serious everybody involved took this movie. It definitely adds to the overall quality of the movie and its nice to see that this is a movie that took its audience serious and didn't treated them like a bunch of popcorn-eating-no-brainers, who only wanted to see lots of blood and nudity. The movie is not like that at all, even though the first 15 minutes would still suggest otherwise. Perhaps it was all deliberate and in the first 15 minutes they were like; 'this is what you expect us to do' and what after that follows was 'but this is what we are going to do with the concept'.
Thing I also liked about the movie was that it didn't featured one main, heroic character, in it, who saved everybody. instead there is a wide range of different characters in this, who all, just about, share an equal amount of screen time. None of them is pretending to be a hero, which also lets all of them all feel somewhat realistic and human-like.
On the downside; the special effects in this are pretty horrendous. Sort of funny that after 40-years, "Jaws" still has the most convincing looking shark in it. This movie too often relies on CGI effects, which aren't exactly of the best quality. But still, as far as shark movies go, this definitely is being one of the better ones, believe it or not.
