Frankly, no, not when the "enemy" is not once shown to be capable of any kind of compassion. Suppose that, during WW2, the fate of the world came down to zombies vs. Nazi Germany. Sorry, but I'll always root for humans, no matter how corrupt, over literally mindless bugs/creatures.I find the movie to be a pretty sharp and interesting satire until the last mission, when it suddenly becomes exactly the sort of rah-rah "ain't war an adventure" flick that it earlier ridiculed, as it certainly seems that the protagonists achieve what could be a defining victory in the war. If the filmmakers had had real stones, everyone would have died abrupt and meaningless deaths, but the demands of commerce evidently required some sort of upbeat finale.
That's the kind of 'upbeat finale' that's appropriately disturbing, though. Fascism triumphing over its enemies is more unsettling then it being defeated, no?
If there had been hints that the bugs had their own civilization, feelings, love, etc., that'd be a different story, but that's not what the movie presented.
I was rooting for the humans in the end too, but for me, that's one of the movies assets. You end up rooting for a fascist empire yourself, in just the same way as the humans in the movie do, and cheering along. And then you remember what the Federation is all about... and you STILL cheer along because it's just good fun. Elegantly effective ending, and a beautiful depiction of what propaganda does, when two opposing ideologies clash (fascism and communism in the movie, but could really be anything).
