Exactly, while DC was doing major damage to Batman...and possibly permanent damage to Superman...Marvel wasn't making movies. Years later, not only did technology improve, but the mindset on what a superhero movie should be, changed. This led to more "serious" films with better effects. Had X-Men been done in the 80's or 90's it would have been a poorly done day-glo nightmare. Instead, DC blazed that trail and made the mistakes...and it destroyed their ability to make films. Marvel capitalized on the new technology and respect given to the properties and made some great films. Marvel has also stumbled in the process with some crapfests. Now, DC is beginning to convince the higher ups that their properties can be done correctly and profitably...and look good thanks to modern technology...and slowly the execs are starting to warm up to the idea.
I certainly hope that's the case, and yes I don't think a GL film in the 90's would have been very good, as CGI was expensive and in it's infancy. I remember being blown away by Jurassic Park when I saw it in the theater. Now almost 20 years later, the CGI looks dated, but still very enjoyable.
Marvel in the 90's almost went bankrupt, do to the comic bust in the early 90's. Alot of people were collecting books with the thought that they would be a great investment. Of course the reason the Golden and Silver age comics are worth so much is due to the scarseness of finding a good print. When people found out that there were 3, 4, and even 5 runs of printings of so-called "valuable" books, the buble burst, and Marvel was forcing to sell movie rights to it's characters to generate cash, which led to the Punisher, Captain America, and Roger Corman's Fantastic Four.
This crash effected DC too, but because they were a wholy owned subsidary of Warner, they weren't in jeopardy like Marvel was.
After the restructuring and Avi Arad came to the forefront, he really did a great job of marketing these characters to the public. The problem was that for all the Success of the Spider-man movies, Sony saw the lion's share of the profits, and they seemed to lose control of the characters with companies like Fox.
The need to form Marvel Studios wasn't to create the so-called, "Marvel Cinematic Universe" but to gain control of the characters, and be able to generate more money for the company.
That brings us to the Disney Merger. The fact is a movie studio that only makes comic book movies wasn't going to survive, despite the success of Iron Man. The merger with Disney was to give stability to the company where they can be more creative.
The problem as I've mentioned with DC and Warner, is that Warner has way too much controll over decision making. Someone mentioned that Warner wanted to take the rings out of the GL film. That pretty much shows the mentality of the board room at Warner.
Hopefully the'll start making some of these other properties, before people really do get sick of comic book movies. That would be the biggest shame of all.
