A (what else?) nutty scientist creates a half pterodactyl, half barracuda, which breaks free and goes on a killing rampage. To try and battle it they set free the half shark, half octopuses and soon the two are killing countless swimmers and battling each other.
SHARKTOPUS was a pretty bad made-for-TV movie but I'm sure the concept alone got people to tune in so we were greeted with this sequel, which is slightly better but that's really not saying too much. When it comes to these types of movies, one really shouldn't expect quality but instead they should just hope for something entertaining. With that being said, SHARKTOPUS VS. PTERACUDA isn't a complete success but there are enough campy moments to make it worth viewing once if you're a fan of these types of films.
The highlight has to be the cameo by Conan O'Brien. O'Brien, the actor, is quite annoying playing himself here as he simply goes too far over-the-top but what follows is quite campy and actually hilarious. I'm not going to ruin his fate or what happens but it's quite funny. Robert Carradine is decent in his role as are Akari Endo and Tony Evangelista as the heroes. There are a lot of fun and gory deaths throughout the running time but after a while the movie really gets boring and it starts off rather poorly. Too many slow moments keep this from being more entertaining.
