Well, where to start... This movie is a mess. A good kind of fucked up mess. This movie carries on the crazy roller-coaster ride from the anime and bring another kind of horror to the realm of live action. It's very graphic and I'd recommend you to be 17+ before you watch Himitsu: Top Secret. This movie is fucked up and I'm serious. For the plot and acting, you don't have to worry. You might say that Ikuta Toma wouldn't fit Maki's shoes but you'll be utterly wrong. Toma carries Maki's grief and guilt so well that you won't mind anything else and Okada Masaki is perfect for Aoki. Just don't expect subtle shounen-ai like in the anime because their relationship here is just like any proper boss-subordinate. The movie itself has squicks that normal human would feel like ready to vomit about. I'm a squeamish movie-goer and I don't regret ever watching this movie, even though I want to throw up my dinner afterward. Let's just say that if you ever watch the anime, you'll get the same sense of dread if not more because hey, we're talking about a live action here. You want psychopath? You get one. You want a strong but vulnerable Maki? You get one. You want a plot worthy of Pink and Gray? You get one.
