Good try, but NO! Just because there is a good amount of gaming fans who THINK this would be a good idea DOESN'T MAKE it a good idea. Hell, I think Baten Kaitos would make a great movie, but I don't think it would do well outside of the gaming community, so I will let it go. You have to use logic to realize that the movie would have to reach out to a bigger audience than just gamers. Wait to see if movies for video games like TLOZ or the Metroid Prime series end up being major blockbusters. Then consider this idea. Also, this game series has barely any storyine, unlike TLOZ or MP, which basically are all storyline. So what if the Subspace Emissary thing turns out to be good. It won't stray away from the fact that this game is just a normal fighting game collaborating many Nintendo characters. You can obsess over a video game, sure (that is why we have Smashboards), but taking it to the theaters is a bit much, don't you think? This was meant to be a game, nothing else but a game. Enjoy it. Don't ask any more of it. It is good enough as a game.
P.S. I see Samuel L. Jackson as more of a Luigi (Billy Bob Thornton as Mario, and Keanu Reeves as Pit. HAHAHA!)
This has been a REALITY CHECK, and we are through.
