Acting is bad, story could have been interesting but writing is not great. Special effects are decent at times but sharknado level at others.
Characters are not very well written or interesting, I was really rooting for the shark, in particular in a scene with the stupid 20 years old girl. Most of the time this takes itself too seriously considering the result.
It feels like two persons made that movie with a mix of decent and really aweful scenes.
I would say it's nearly fun and only saved by the nice number of death, fine to watch on netflix as a last resort but not worth any money.
