The first 1/3 of Sharnado puts your Brick and Looper to shame.
I can't comment on the rest of Sharknado because I stopped watching. NOT because it wasn't the greatest movie of all time, but because since it was so much better than Brick and Looper, it was like I was watching 300 movies worth of greatness in 20 minutes. I overloaded and had to stop or else I would asplode.
