Sharknado's definitely not a good movie, but I have found it fun both times I've seen it. It's very much so below average, but if you can have fun with it, then you might be able to get by okay. Special effects are utterly horrible, but it's a Syfy/Asylum flick, so what else would you expect?
What are your thoughts on this rather ridiculous movie?
