I've seen a few reviews about how unrealistic it is about sharks living in freshwater lakes. There have been sightings and attacks in the Great Lakes, Lake Ontario, Trinity River. Lakes in Louisiana and California. So that part is probably the only true and good thing about this film. The public needs to be educated, but since this movie is more an SNL Jaws parody (without the comedic approach) they really dropped the ball. And really, it's not even about sharks. It's about a small Texas town with corrupt political figures and a game warden struggling with alcoholism, divorce and being a bad father. The sharks have small guest appearances a couple times and then some plastic fins a few other times. Nope. No thanks.
*The people behind this film have a funny stereotype of Texas. But seriously dude, we're not a bunch of beer drinking till we fall over drunk people.*
