That the 'Sharknado' series went for six movies is a triumph of human commitment to a tired old joke, but all things must come to an end - and so it goes that 'Sharknado' is ending.

Not with a bang, but with cameos from Alaska from 'RuPaul's Drag Race All-Stars', Judah Friedlander from '30 Rock', Gary Busey and Tara Reid, Ian Ziering (again), and CGI sharks. Oh, and Tara Reid clones. Clones and clones and clones of Tara Reid.

The movie sees Fin (that's Ian Ziering's character's name, by the way) racing through time to stop sharks from attacking Merlin's castle, the Wild West, World War II and probably the future because who actually watches this stuff anymore? Seriously, like.

'Sharknado 6: It's About Time' (just got that now) premieres on SyFy tomorrow night and will likely appear in a DVD bargain bin at a petrol station in a few months time.
