I gave the system a 4 because it gives a solid framework for a superhero game and allows for telling some really fun stories, but it does require a lot of DM adjustment and house-ruling in order to make it fit the table. The random generation system can make some relatively weak heroes at a table with a nigh invincible supermensch. The problem with this is challenging the overpowered PC with a villain that can oneshot everyone else.

Regardless, there are some flaws, but it is a very fluid and simple system that allows for some changes without it becoming something with Palladium levels of complexity.
