The real prize in this one IS the six-headed shark, which is a fun CGI that's much better than its 5-headed predecessor, although disappointingly used at times. The movie, the 4th in a multi-headed shark horror series, is also a step-up from last year's "5-Headed Shark Attack". But even as far as bad movies go, the storyline built around the characters here was pretty scattered, and attempts to build the characters fell pretty flat, leaving the watcher to really root for the (apparently amphibious?) 6-headed monster. While some of the acting is expectedly bad, I do want to offer some credit to Megan Oberholzer and Thandi Sebe for holding up their respective characters very well, all things considered.
It's fun enough and worth a watch, but it really falls short of it's potential. I'd love to see the 6-headed shark again (as opposed to just adding another head) because the CGI for this fella was really fun, but I've already assumed he'll reappear with a scorpion-like sharkhead tail (7th head) for a 5th installment in the series.
