Superman is too overpowered. So what’s the point in a super team if you have one man that could hear the whole world, lift entire skyscrapers, breathe in outer space and underwater, fly faster than sound, near invincible and heat blast you into oblivion. That means there is no point in characters such as Aqua Man and Flash. I like when the turn his powers down by a lot. Like him barely being able to carry a plane or be able to be beaten down without kyrptonite it just makes the Justice League more interesting and meaningful, which is one reason why I prefer marvel.
