What. The. Fuck. Why the hell did we get a trailer that makes Big Hero 6 look like every other Disney/Pixar movie, while the international trailer and specifically the Japanese trailer, actually gave parts of the story and showed character depth? For those who though "oh, they're killing parents again" nope, they switched it up and killed his brother!!! Still... Disney stories only know who to begin with death. I now understand that Baymax was the dead brother's creation!! I just thought he was something the asshole kid created because he was an asshole. There's some boring discussion about the trailer and some clarification of the scenes since it's in Japanese, but really you get the gist of it just from watching the trailer. I'm going to have to check with my friend in Japan to see if they're actually calling this film Baymax or if they're just promoting it with the character. http://www.youtube.com/watch?v=o80emfAy-QI#t=336
