Stremio works on android TV. I use the Stremio + RD + Torrentio setup, it’s great for essentially mimicking the Netflix experience in that you can sit down and browse movies/series, watch trailers then just select something to watch right then and there. It’s intuitive so my family can use it easily.
If you mainly watch movies on your PC/laptop then there may not be that much material gain from the above setup - but it is a good option if wanting to fully replace the Netflix-esque experience.
