I just wanted to elaborate on this because it seems people have a hard time to separate recognition from natural success.
Avengers is a natural success, people continue to bash it over a non-existent live-action Justice League film. Now, that's not me saying that I'm not looking forward to a Justice League film in the future but I have a hard time backing up everyone's statements on how a Justice League film is "better than Avengers" just because they're "more recognized". Heck, this applies to the upcoming Superman/Batman movie - these characters most certainly are (arguably) two of the most recognized characters in the face of comic-book heroes but why is it that just because they are more well-known, their film will automatically be better than The Avengers (and it's sequels)?
A World's Finest film can be a failure if it wanted and people would still consider it better quality than The Avengers (or any other DC rivals) just because of the film's characters. There's been a lot of talk on this forum about this crap and it's getting tiring. Yesterday a Namor/Aquaman forum opened up over who's more recognized in the face of the general public and it turned into a war over who's a better character/who comes from the better company.
I certainly hope people will eventually see the light on this childish-banter.
