4* if it wasn't for the video player. It is unintuitive, worse than the old one and requires several clicks to do anything. I needed three clicks to pause the video when I was on my feed. The videos randomly decide to start playing again after you pause them. Sound will randomly come on again if you have paused and hidden the videos to read the comments. All videos autoplay now regardless of settings. It's like 1 step forward, 20 steps back with this.
