You can change the UI design to whatever you want with a custom CSS. Can make your own or there's a plethora of themes on GitHub. I remember trying one that replicated the Netflix app, and don't hold me to it but I think I saw a Plex one as well.
Also, regarding the metadata, there are options that auto populate it for you. Idk how it does it, but my haphazard library of torrents all had accurate metadata AND it downloaded the subtitle files as well.
