I wish they had explored Omega Sentinel more and really juxtaposed her properly with Moira when she was still a mutant. We also should have had Moira book because we saw so little of her before she was degenerated into a moustache twirling psychopath! Making her a robot then also took away from what was Omega's USP as a female cyborg ally turned enemy. I keep forgetting that Omega is actually the true creator of Orchis, so much time has been spent on Essex and Fei Long instead.
