Im sorry but heres my opinion on the matter. Being a huge fan of movies overall I get so anxious seeing trailers and stuff that I cant hold myself and wait for them to air in my country. Im brazilian, so the majority of the movies air around a month to two months later than the original air date on the USA, and that time is something I can NOT deal with.
For the past year or so Ive been watching movies on the internet around 1-2 days after they air, depending on how big the movie is, sure its cam quality, it sucks, the sound is weird, it sucks as well, I know, but once you get used to it its just like seeing a movie in the theaters, hell I even prepare some popcorn and plug the laptop onto the TV for a bigger screen and overall better time.
On this instace its a litle bit different. Its a movie that will only air in Japan on Dec 6th, less people around the world will see it on this date, there will be no subtitles in english and the japanese voice will be a pain in the ass for those that dont speak the language like me, but knowing Naruto and the overall script of the movie because of the spoilers we have been getting Im sure some of it we will be able to understand. Sure, most intese driven moments of dialogue, confessions and stuff like that will be really hard to get it, but just seeing those images, lets say Naruto and Hinata kissing for example, will obviously be emotional anyway. Sure it might take more than 1-2 days to be in the internet with the quality listed above, but will be around next week on the internet, Iam positive on it and I will definately watch it.
Cheers.
