My biggest issue with the show is the characters. With the amount of retconning going on, you would have thought the writers would be smart enough to just make new characters instead and maintain the integrity and legacy of beloved characters. But then again, the "script" for this show had 265 drafts over 8+ years and they still landed on garbage.
There is nothing about this show that feels even remotely familiar to the Halo we know except the art/costumes and Cortana. Not even the Chief.
Paramount does not understand what makes Halo special.
