From the sales page:

With a few notable exceptions (Goodburger 2), we all know that sequels never reach the heights of the original. So just take a moment to process what that must mean for Jurassic Shark 2: Aquapocalypse. Yeah, we know. It’s sobering stuff.

Jurassic Shark, if you’ll recall, was about an art heist that was occasionally interrupted for some light CGI chomping. The stolen painting, which we can only hope involves a group of canines gambling, remains lost in the ocean. Remember how we said that everything about sequels was inferior? Well the ocean must have held out for a bigger salary or a nicer trailer or something, because in Jurassic Shark 2, the ocean is very obviously played by a lake.
