I just started watching this yesterday. How did I never find out about how good this show was? I've been binge watching it like crazy since then. Everything is just so so fascinating. The whole Gem story arc is amazing, and my favorite character would have to be either Steven or Pearl. Such amazing characters, such an amazing soundtrack (like something you'd hear from an Anime, any song involving pearl is amazing and uses the piano mostly for some reason). Such a great show.
If you're not watching this, give it a shot. Things really get interesting as you progress, and sometimes it'll kinda hit you in the feels.
