For whatever reason I could never get into sense8. I remember when it first came out on Netflix and I was like "This looks cool" but then when ever I tried to sit down and watch it I always felt like I could never give it my full attention and it was a bit more deep/heavy and story driven that I could give it. I would say season 3 is still possible it just might be while. In this day and age I feel like a show is never done. So many shows have "gone off the air" only to come back many years later. As the fan base grows from people finding it on Netflix it could build up enough demand for a third season.
