I understand the point of Disney having Marvel Studios (separate budget, etc.), but Warner Bros. has more problems than that. 1.) It dragged it's feet. The start of the Marvel Cinematic Universe started with Iron Man in 2008. The DC Extended Universe (or whatever we're supposed to call it) started with Man of Steel in 2013. Marvel was already onto Phase Two when DC was trying to get off the ground. So to compete directly with Marvel was never going to work. Warner Bros. was trying to play catch up from the start. 2.) The movies were just a general mess. Let's put ourselves in a world where Marvel Studios doesn't exist and Warner Bros. is the only studio putting out superhero movies (the same movies they are putting out in this world). In my opinion, they would still be panned because the movies just aren't very good. It doesn't seem like they are building up to anything, rather, the movies seem like a transparent ploy by a movie studio to play catch up to another studio. 3.) Too much studio meddling. Trying to change the heart/tone of a film in post-production is not an easy thing. Having to do multiple re-shoots, too much editing, etc. Let the filmmakers be filmmakers. I don't know, I prefer DC characters over Marvel characters, but the majority of the DC films are just plain bad. I'd really like to see a Batman Elseworld universe, but I know that's not going to happen. Not a big enough pull for general audiences.
