Compete with what? Disney can throw together an animation of Spiderman and Mickey Mouse dancing to 'Chim-Chimeny' sung by my deaf grandmother and it would still sell.
If anything it's definitely going to strengthen Marvel and the amount of media it produces. Whether for the good of keeping
'The Marvel Way' or not, Marvel sales are going to increase regardless.
My opinion at least.
DC in my opinion was spiraling down hill until recently in the past ten years. Their recent comics and definitely movie adaptions go to show how much stronger they're coming out in the media industry. Nearly every gaming mag and review site has said that Arkham Asylum is the greatest Batman game of all time...though it does help to have
The Force behind the Joker.
I think Marvel was feeling the heat. Honestly their animations and recent movies have only been 'alright' or just plain 'rent once never look at again.' I think this move is going to do a lot for the company, and I can't wait to see what they do with the IP's.
