It's an amateur film, as simple as that. It got made with no real money or talents involved. It's a cheap looking film, with bad acting, terrible dialog and a script that you could barely even call a script at all. But luckily the movie knows what it is and it isn't taking itself very seriously neither. It's never trying to be a clever or realistic but instead one that's silly and fun to watch. In a way it works but I just really can't call the movie a good one as well. It's just a too poorly made movie for that.
The movie is following a whole bunch of different story lines and characters but to be frank, I had no idea what was going on in this movie. I had no idea what each character was up to, or what even his/her name was. I also still have absolutely no idea where the shark came from and why he kills people in shallow water in lakes. It's also crazy how the shark is supposed to be a mega-sized one, yet he (or she?) looks no bigger than an ordinary great white shark. And why does he fly exactly? I just really don't know and it shows you how confusing and nonsensical this movie gets to watch at points.
And while the movie is only 70 minutes short, it's pretty obvious that the film-makers were running out of ideas pretty early on already. All that basically happens in this movie is that one or two people keep going into the water and end up getting eaten by the shark. Not much else is happening really and it's annoying how scenes feel stretched out and most of the time utterly pointless as well. The movie is filled with needless character, pieces of dialog and scenes that just don't add anything to the story at all.
It's a cheap looking film, which does not only shows with the special effects but also look- and sound quality in general. It's as if they couldn't even afford a tripod at times and shot all of the scenes from the hip, without a real plan. 'We'll fix it in post-production' must have been one of the catchphrases often used by director Scott Patrick while shooting the movie.
I'm sure that the film-makers were having plenty of fun while making this movie and I'm also sure that to them this still remains a very fun movie to watch but for everyone else it's just a cheap, very amateurish movie, without any real creativity or good and memorable moments in it.
