Everyone is entitled to have their opinion, of course. But if you really dislike them that much, just don't play them.
Personally I dislike it when games (or films, TV shows whatever) decide to stop taking themselves seriously and go the opposite route and just play everything for cheap, dumb laughs. Best example - the Command & Conquer/Red Alert series, the cutscenes became painful from Red Alert 2 onwards.
"I can take you with one gun tied behind" in a thick country accent or when responding to a call for assistance, the happily yelled "This sounds like a job for....ME!"
I found most of the voices of these characters rather daft and irritating, especially the one who talked like Gomer Pyle ("Dey caaayn't stop mey!"). I doubt any fighter pilots in real life talk like this, even ones who come from the Deep South part of the USA, they're supposed to be educated officers, not redneck grunts.
That's...kinda the point of RA2 though, it's supposed to be campy. It's part of the charm. I think RA2 did some really great things with their FMV - you only see the characters two or three times total for only seconds at a time but the over abundance of their personalities really makes it clear who they are supposed to be.
It made me so angry when the game about space cats bullying space birds in space stopped taking itself seriously.
Going on off a tangent here but of course I realise Red Alert 2 was trying to be campy, but deliberate, over-the-top campiness doesn't always work for me, the RA2 cutscenes said to me "we know our audience are 13 year old nerds, so we're not going to bother doing anything properly".
On that note, are there ever any Terran casualty statistics for the Kilrathi war? I've seen some discussion about the Kilrathi side of things in relation to why it was so high, but I'm not sure I recall anything about Confed casualties (I guess I shouldn't say Terran since there are other non-humans serving with Confed?).
I don't think that was their intention with Red Alert 2 at all. You're making it sound like they didn't care, but I think the game universe speaks for itself - there is an incredible amount of story and characters revealed in RA2, and if they really didn't care and so just made it campy because every 13 year old would by it that material wouldn't have made it into the game.
