Made for, well, possibly no money, starring people who probably have never actually seen a film before - such is their lack of acting ability, and with a plot/script that was, at best, possibly driven past the people involved, this is terrible.
But, in an honest way. It's shit and it knows it is. It tries to have fun with it. There's a big difference between doing the best you can with whatever meagre funds and talent are available and intentionally trying to create 'rubbish'.
Sharknado 5: The Sharkopalypse? Fuck off forever.
A bunch of mates fucking about on a northern industrial estate with cap guns? Yeah, why not.
