I have to agree with W. J. Howard. The Sharknado movies are awesome! The only question is how she compares the latest offering, Sharknado 4: The 4th Awakens, to the others. I don't see how she could possibly give it a thumbs down, but you'll have to go to the link above and read her stellar review.
