The funniest part was the beginning with the grandmother. As soon as the main Tron gag starts, it gets boring. Well, maybe not boring since there is a lot of content crammed into a small space, so it's not like it wastes your time or anything. But the writing seems amateurish and uninspired. It seems like you just started animating without any real solid ideas to base an animation around. I'm not sure what the point of any of this was.
