OK I'll give you that, I'll still stand by it took them forever, 40 years is a long god damn time.
X-men was good, not great, still not making any headway.
Sorry but you can't really use the 50 years argument. It took DC 40 years to make a Superman movie in 1978. So really you should start there on where Marvel should have gotten off their ass and started make good movies.
Even then you have to realize that Marvel didn't have the luxury of being owned by a multimedia conglomerate like WB.
