First season was absolutely terrible. Helmet? love story? Covenant human??? Who approved this absolute trash interpretation of halo?
Second season started strong, but just nose dived on the reach invasion. Watching "The demon" crawl on the floor helpless was just laughable. Again no suit and more bad acting.
This is so derailed lore wise I'd put it alongside the Avatar Airbender movie. Laughably bad at what is trying to do. And a direct middle finger to the fans who liked halo.
