The guy's an idiot and there's nothing interesting to it imo. Felt like his only purpose was to emphasize Lasky's good heart and probably to make you hate Palmer a little less, instead of creating a complex relationship between MC and the UNSC. Del Rio felt like an unnecessary throwaway character.
The issue with Del Rio is that he's just a foil, and a somewhat nonsensical one.
His character was incredibly poorly written and acted to the point of being utterly ridiculous.
They might as well have called him Captain Antagonist, because he was absolutely nothing more than a two dimensional plot device.
AAA++ assessment. I guess they even wanted the TTUVAPORs of the world to "get" that they weren't supposed to like the character.
Personally I don't love to hate him. He's just a meaningless character to me who is a waste of space. He frustrates me more than anything because his actions bad attitude don't make any sense.
He was an asshole for the sake of being an asshole which isn't interesting at all imo. If he had some kind of legitamate reasoning then that might've been cool, but he was completely 2 dimensional and had no redeeming qualities.
Too bad my ass got SERRRRRVED... :-/
