What movies or TV series have you watched more than 5 times?

At first, I wondered how to answer this and link it to a scientific subject – and then I had a light bulb moment. Sci-fi, anyone? Ironically, I don’t consider myself a fan of science fiction, and yet I am inexplicably drawn to it anyway.
To answer the question, I’ve probably watched Smallville more than five times, or at the very least specific seasons of the show. Smallville was a show detailing the life of a young Clark Kent, a character more commonly known as Superman.
I’m always fascinated by the science of Superman. Is it possible for a man to fly, and what would the circumstances be? Is it possible for a physical being to be harmed by a rock?
According to Science World, one reason Superman is able to fly is that he’s from another planet where the gravitational pull (i.e. the phenomenon that keeps our feet firmly planted on the ground) is less than it is on Earth. That is definitely something to think about the next time someone tells me that Superman isn’t cool because he’s too powerful.
In the meantime, I’m going to hunt for a copy of ‘The Science of Superman’ by Mark Wolverton and see if it answers a question that’s been burning in my mind. How does Superman shoot fire out of his eyes?
