Well...like the one above said,the first 2 电影院 are basically like a summary of the whole 日本动漫 just with a more...unusual environment/background,although i'd suggest to just watch the 日本动漫 then watch the 3rd movie,Rebellion unless 你 wan't less watch time...? (i don't know if the times in the 电影院 are any less though,i just skipped it after watching like 20 分钟 of both)
