Millennium (TV series)/YMMV

The TV Show:

 * Awesome Music: Mark Snow provides a beautiful opening score and the Soundtrack boasts the likes of Nine Inch Nails and Portishead.

The DC Comics series:

 * Fridge Logic: Revealing all of your sleeper agents at the same time may not have been the best of ideas.
 * Also, you'd think those agents would have done something more than just wait until being told to attack (and get their asses beaten.)
 * Marvel's Secret Invasion used this same idea decades later... to the same results.
 * Exactly, how did the Guardians determine who got to be a Chosen One? There seemed to be no distinguishing quality; one of them in fact turned out to be a racist bigot and was rejected. Another (Terra of the Teen Titans) was already dead, too. You'd think the Guardians would have known that.
 * What an Idiot!: Harbinger, a character left over from Crisis On Infinite Earths, records the history of the universe in a device... which she leaves adrift in space for anyone to find! It was thanks to this that the Manhunters found out the secret identities of all the heroes.
 * Made worse by the fact that she barely gets reprimanded for it, and in fact joins the New Guardians.
