superhero movie about a kid with powers but is a whimp-- goes through exercises to improve into a true tough guy that stands and fights when others flee--
line from the mentor character: "It doesn't matter if you have super
powers or not-- If you scream and run from danger or a challenge, you're
no different than the people you're supposed to be protecting..."
JACK of all powers
master of none-- can only run 70 mph, slightly faster than a cheetah, can fly but only so high, etc. etc.
final moral of the story is this: from small things precedeth that which is great.
