Quest For Peace > Man of Steel
In fact I've watched Quest for Peace more time than Man of Steel. It's garbage I know is so bad it's entertaining while Man of Steel is garbage I just can't be entertained at all.
The premise for Quest for Peace was actually quite interesting: in a world threatened by nuclear holocaust, only someone as powerful as Superman can get rid of all the atomic bombs thus ensuring world peace. There are some very inspiring moments, like Superman’s speech at the UN or his examples of idealism and goodness, but overall the execution of the concept is inadequate. With the smallest budget of all the four Superman movies and a shoddy production, the plot holes and bad narrative choices were too evident and because of that the superhero franchise was negatively affected.
