I have to admit it, they are bad, but so bad I like to watch them, at least parts of them. Love the scene in #2 when Al Franken and Matt Lauer skewer a shark live on air, then return you to regular programming. Or #4 when a Kansas sharknado whisks up a bunch of cows, which the sharks proceed to munch on.
Silly movies that will never win any awards. But sometimes that’s all you want. And I will watch #6 later this evening,
There ought to be a “Guilty Pleasures Award” for movies like this.
