Great Movie, One Scientific Mistake

Rating: 9/10 (7 December 2015)

The movie was really great. Being more of a DC fan myself, I found myself loving this movie. I didn't think that it will be much when I first saw the posters, but I ended up really enjoying it.
The only problem is (perhaps I'm not understanding it right, if so please correct me), the movie states that the suit shrinks the relative distance between atoms. So how on Earth does a person go into sub-atomic wearing the suit? No matter how short the distance is, an atom will always be the size of an atom, that doesn't change. How can ant-man go smaller than an atom?
Love Paul Rudd's performance in the movie. Definitely worth watching.
