When a mad scientist mixes the genes of a killer whale and a wolf, it creates the Whalewolf, and it's up to Sharktopus to stop it.
This was actually pretty decent. Sure, the CGI was a bit cheesy, but the acting was decent and the production was good too. The story was a bit silly but it never tried to take itself seriously anyway. For a "low budget" film I've seen much, much worse.
