I'm usually a tough critic, but I really enjoyed this movie! This is one of few Japanese movies (And I've only watched a few)that I entirely enjoyed the whole cast and acting. Most importantly, Acting; because in other dramas/movies I feel as if the actors sound/feel too forced, but in Golden Slumber, the acting was superb! And Masato Sakai did an AWESOME job. He's an amazing actor, and I can't wait to watch more of his dramas/movies. Another thing I loved was that this movie was in fact named after the song Golden Slumber by The Beatles, and you'll understand the meaning of it throughout the movie.(as well as it's connection to the story). Also, while watching, it helped when I payed attention to the character's names and faces because it got a little bit confusing and the quality of the movie I found online wasn't too great so I couldn't clearly see the faces. As for the story, it's not in complete chronological order, and it expects you to understand the scenarios/situations/conversations using deduction, so watch with your brain ;) I recommend to anyone who enjoys comedy/thriller/suspense/mystery-esque themes.
