Will DC ever be as successful as Marvel?

If they stopped trying to compete and keep up with marvel and just take there time with there movies then yes I think they will but tbh wb is all about money over quality

I don't think they will. I honestly prefer DC over marvel.

I will Marvel at DC if that ever happens.

Yes

I don't think any comic will replicate the Marvel Universe. Downey Jr was the capstone of a brilliant production team and cast.

No I don't think they will

Probably not in the movie industry
