I wouldn't say Superman was weak
Some thread here say that they made Superman weak and I don't think that's the case.
I'm rewatching the show (it's been a while since I saw it) and I'd say that they just made him kind of dumb when it comes to him the powers. Many times you make yourself wonder "why didn't he use that or he would've avoided it if he just..." etc.
I get it why they did it, it would all be over so quickly since he's, well, Superman but it still makes him kind of dumb.
For example, the War World episode. There are scenes where he's being chased by robots and he doesn't use his heat vision at all, he'd take care of them with no problem if he did that (he only uses heat vision once in that episode and it's just to melt one small axe).
There are also many times where he could've used his super speed to avoid a punch or something or even his super breath, but those powers seem to be greatly underused in episodes I'm watching atm.
Like I said, I get it why they did it, but I think they should've think of some better scenarios because half of the time it just makes him seem like a dumbass for not using a specific power.
I'd say the Flash suffers from a similar problem. He's super fast but villains always manage to take him down (hell, sometimes it isn't even the villains). I get it why they did it, but again, he gets taken down in silliest ways.
For example, in the episode with Hades there's a scene where a sorcerer Faust uses his magic ray to destroy the ground so bunch of rocks are sticking out now. He shoots the ray clockwise and Flash was running towards him. Not only would Flash see well in advance what he was doing but he could've easily jumped over those rocks. Instead, he simply trips over them...he trips.
That's it.
I think there's also an episode where he gets taken out by a small rock that hits him in the face.
Come on, Flash.
I don't mind that he gets hit etc. my problem is that they couldn't think of more dignifed ways to do it? He looks like an even bigger dumbass than Superman.
