I have no problems with Godzilla and Kong teaming against a common threat, I just don't want it to happen in Godzilla Vs Kong, but for the next film in the franchise which I hope will be a Destroy All Monsters type film.
Batman Vs Superman is a perfect example. In my eyes, that movie had no business being titled Batman Vs Superman because the movie's focus was not the battle between the two heroes, but it was just a prequel to the Justice League. The movie was crambed with too many ideas and too man characters.
This is not what I want for Godzilla Vs Kong. I want this movie to be simply about Godzilla and Kong, and somehow the two coming together to battle. If other monsters are going to be in this movie, it should be no more than a cameo or a very small role.
It would be an awesome idea to have Godzilla, Kong, Rodan, Mothra, etc to team up against King Ghidorah (and other vilianous monsters), but this should not happen in Godzilla Vs Kong. I hope Legendary/WB learned from the mistakes made by Batman Vs Superman and give us a great and satisfying battle between the two titans and prove who is truly the King of the Monsters
