I'll agree with you that COD BO2 was the best COD but I don't think its because it wasn't to futuristic(BO3 wasn't that bad) but because of the time period. It was thelast COD before newer consoles came out, there was still a lot of toxicity which you won't get today since its frowned on now along with you having to be in gamechatand it was definitlyinnovative, most of the COD's after that where definitly trying to recreate that feel.
