It wasn't a bad film but I felt they never really developed any of the characters enough for me to care about any of them. Pretty much everyone in the film came off as a lowlife even the cops. Not a film I would ever revisit personally.
The pacing was a little slow and I personally didn't find it to be all that scary, maybe a little creepy but nothing terrifying in my opinion. It has a few semi scary moments and a few shocking scenes but I've seen worse.
Clearly this was no Jaws or even Deep Blue Sea in my opinion. Just another shark film about an even bigger and more deadly shark and a slight twist I guess...I can't say I was bored but I won't be watching this one again. I'd pass on this one folks!
