May be you can say this movie because the video's length is around 40 minutes. But I would rather to say this is a documentary about cosplay in western. This video contains much cosplayers in some exhibition. From anime (Made in Japan) until local cartoon. At the beginning it shows some anime cosplay, then the introduction, explaining about what cosplay are. Then there would be peoples were interviewed, answering the sub-tittles. What is cosplay, how to get the costume, competition, characters act, and so on.
It's not too bad video, but may be too boring because I rare hearing music, only people talks and whispering.
For those whose really want to know (more) about cosplay, watch this video, then let your knowledge increase.
For those whose already know (too much) about cosplay, watch this, and criticize it
