Man I can not believe in 2015 those CGIs are still allowed to appear on screen. I do understand that sometimes you're on a tight budget, but come one, if you going to make a movie about a shark, well...these guys right here couldn't even make a decent flipper. I mean seriously, even that is pc made, which makes this movie, quite a joke.
There is a plot to it, there is an well known actor but not the star of the movie, and a quarter of execution here, as well as all the boredom you can imagine. It wanted to be a shark movie, and it failed by all means possible, and the shark... it was bad.
I mean, I'm going to recommend you Shark Night 3d, or Bait, both cheesy movies that are so bad they're fun, and of course, little baby Jaws compared to Shark Lake.
Cheers!
