This is such a step up from the anime adaptation. Well, for me, anyways. This feel more like the story of Kousei and Kaori than the anime, which spent a lot of episodes on developing side characters that weren't as interesting (like the other pianists). I am also glad the mother drama wasn't as exaggerated in this. It was still a big part of Kousei's character, but in the anime it got annoying reaaaaaallly quick.
Overall, this is the definitive version of Your Lie in April to me. The actors and actresses did a fantastic job and while some interesting things were cut from the anime and manga versions, the experience felt better me.
I did not enjoy the "ending". It was kind of expected, but Qi Lu's ex girlfriend coming back will just create more stupid conflicts in season 2 :T As if Wan Zi and the other girl weren't annoying enough. Lastly, that cliffhanger was total garbage. >.>
I did not find season 1 to be all that sexist. Some things were off, but the lead character was actually quite empowering. She gave no shits and lived her live the way she wanted (and could, being on her situation). I hope that doesn't change in season 2.
