I always try to stay open minded but when it comes to comic book crossovers...I don't know... that's the only thing I don't really like and honestly don't want to happen.
Each of the "Big Two" have their own different kinds of feel and atmosphere and vast universes and possibilities.
In my opinion, it wouldn't fit together and would take all the fun and uniqueness out of it. Would make it to crazy and implausible. It's like Superman suddenly appears in the Walking Dead universe and start killing zombies with his heat vision...
Don't want to see the Marvel characters in my beloved DC universe.
