Edit - season 2 is actually pretty solid. It still varies a good bit from the original lore but it's highly entertaining and has great action sequences.
Season 1 - So far it's about what you expect from a series based on a game. It just doesn't translate well at all. Moments that would be extremely cool in a game are cheesy and disappointing in live action. The acting is also pretty weak. The show doesn't adhere to the source material at all. Chief has sex with random covenant spy women and takes his helmet off as much as he possibly can. Honestly what the hell is this garbage? I can be ok with deviation from source material if a good story is still told, but wow is this story terrible. They take everything good about Chief and make it bad and then focus on some random civilian girl the whole time instead. Don't bother with this one.
