Why couldn't they...
Made the movie exactly like the games.
Start out with something interesting at the start intro.
And have a character fight through the world flying there in a plane.
Even use the same story, music(even have danger music when a fight is almost over), and have the losing fighter fight just like the games(Ryu constantley throwing fireballs)and have them shout re-used vocals and grunts.
And when a fighter loses the winner taunts him and then says something to him.
And the use the music used when a taunt happens at the end of a match when the other looks beat up.
Why couldn't they do this?
Like they say,Love Hurts!
