If the creative team behind a Super Smash Bros movie nailed that concept on film, the payoff would be so great that there might be hope for other video game movies to get it right themselves.
Also, Pikachu and Mewtwo are just two of the Pokemon available in that game, so the ties to the franchise run deeper than most would expect.
The game’s simple story of combatants from all over being drawn together to fight for victory under a specific set of circumstances is basically The Avengers of video games, and taking that to the big screen would be a feat that would be so daunting, and yet so rewarding.
