Do you know the TV Series The Flash?
I don't follow the Comic Books, but for all Movies and Series I have seen, the Flash is one of my favourites DC characters. Barry Allen is very likeable and I think Grant Gustin plays him really well. Also, the secondary characters are pretty good in my opinion.
Anyway, if Superheroes is your thing, or you're thinking of giving it a try, I recommend this one. He's not dark like some of the other DC characters, since he's quite a positive guy, so if you're looking for something "light", you should start with this one, and he has interesting plots. I find Time travel and multiple universes quite fascinating :D
