Sharknado: Likely to be voted badflick of the year; Birdemic-level plotting, acting, direction, CGI and continuity (the use of stock footage to simulate a flooded-out Los Angeles means the water levels apparently rise and drop dramatically from one second to the next). But then, that's about to be expected. Bring popcorn.
Ghost Shark: A surprisingly better movie than the above (and as such a worse badflick, but never mind); there are some decent touches of direction, and, for a change, we get to see the shark victims' families grieving instead of having them just treated as targets. However, there's enough sketchy CGI and daft continuity to keep fans of the genre happy.
