Who is better, DC Comics or Marvel?
Marvel certainly has the better overall movies these days (with the exception of "Dark Knight Returns").
However, I believe DC has the best super-heroes, ones with piz-azz and flare.
Mike Justice, former employee at Salt Lake's Night Flight Comics, used to tell me simply "DC is better."
Now this is not to conclude that I hate Marvel. I've always been an Iron Man and Hulk fan.
Some argue that Marvel is better because its super-heroes are generally more believable. Well, to that I say: I want my heroes less believable.
In one of the X-Men movies, the heroes fall out of a plane and only one of them can fly. In the DC Comics Universe, that just wouldn't happen and would be a lame movie plot, as many more heroes fly.
If the X-Men and Justice League could battle under independent terms (and not the usual DC-Marvel crossover arrangement), the JLA would win hands-down and quickly.
Even if the JLA fought the Avengers, the JLA would come out on top.
DC may not always handle their characters best, but their properties have the most potential and excitement.
