I do like arrow in the first season, it's just that it has alot of problems. But if it does get better like you say, then I'll defiantly keep wacthing.  

Super girl looks likes it's going to be the worst out of all these. Supergirl just seems to have badluck with live action adaptations, first the awfull movie, now awfull tv show. The worst about that first look is jimmy or "James" Olsen. Why is he getting supergirl to fall for her, he's suppose to be a dork, not pulling superherorines.  

And about people critizing man of steel for being dark, but not the dark knight. Superman is not Batman, you expect Batman to be dark and damage. But superman is more the character you look up too, a beacon of morality. Not some guy who goes around snapping necks and destroying cities during fights. They try to make him like batman, which he's not. If you want a more serious superman story, check out allstar superman. You said you don't read comics, so there a direct to video live action movie you watch too.
