Anyone who has seen a Sharknado movie before knows exactly what you're letting yourselves in for. They're movies best enjoyed with a pizza, a crate of beer and your brain firmly switched off! Whether you believe it or not, Global Swarming takes this franchise to even more ridiculous levels, involving blimps, shark proof helmets, time travel, and of course more sharks than you could shake a chainsaw at.

Never fully away from the public’s consciousness, every shark film since, has owed a huge amount to Jaws, but of course we are now living in an age where perhaps sharks are not the feared beast they were in the summer of 1975. So often the laughing stock of cinema, shark movies have settled comfortably in the realm of B-movie fodder, with straight-to-SyFy shark movies being the most commonplace. However, the aforementioned The Shallows restored some credibility to the genre, and proved it could still be a draw on the big screen.
