Aiming at 10-year-olds doesn't absolve you from actually telling a story.

If you want to have little guy Neville scratch out a win against giant Mark Henry, fine, but even a child should be presented with some reason, some cause/effect why they're in the ring together in the first place.

Just having random shit happen at random time might work for, say, a 4-year-old, but even Sesame Street develops narratives.
