The Halo show has been cancelled after just 2 seasons. The show was a frustrating disappointment. The writers chose to ignore the source material and the storytelling decisions made were offensive to the franchise. The Halo universe is very interesting and it should have been very easy to make a fun and entertaining show based off of the games. I'd love to see a brand new Halo show or movie in the future, however, they need to clean house and start from scratch.
