The best analysis of The Dominion I've ever read.

It’s never really explained why these inherently powerful beings used to be defenseless prey or how they rose to power. But eventually they genetically engineer their neighboring species into happy servitude and, with the help of these underlings, conquer everybody around them and establish what we know as The Dominion. This prevents other species from hunting Changelings for sport and leaves them free to slosh around in The Great Link, which is something between the transcendent freedom of nirvana and a McPoyle-style incest orgy.

I like Odo, but it’s hard to explain why. He has massive integrity and never really comes close to going for Changeling Supremacy and is even willing to give up the great link in the name of justice. So he’s admirable. Pretty well acted, except that in his office as Security Chief he responds to all perpetrators in the manner of a middle school principal. One episode it’s like, “Jake, Nog now tell the truth, were you just hanging out on the promenade to look at women? Well, I’m waiting…” And the next episode he’ll be like, “Dukat, now tell the truth, are you planning to topple my government to re-establish your program of slave labor and mass murder? Well, I’m waiting…”

There's a certain deranged genius to comparing the Dominion with the McPoyles.

That makes a ton of sense.

Not sure I agree with this assessment, but it is a funny image, principal Odo chastising a child Dukat.
