I never cared for the Q episodes -- except for the one where they show the continuum as an old homestead and the universe as a pinball game.
But how Picard kept "outwitting" an omniscient creature and how Riker returned that omniscience when given it just didn't track.
He's omniscient! Negotiating with him is like waiting for Wowbagger.
Q wasn't omniscient. He was a trickster god. More or less a reflection of the entire 24th century unconscious mind and in many cases Picard's unconscious mind specifically.
Often times the unconscious mind represents itself to the conscious mind as being omniscient because it is a broader expression of the conscious mind and from the conscious mind's perspective it may as well be omniscient. And, in fact, it is usually the conscious mind that just assumes the unconscious or subconscious is omniscient.
Picard's disdain for Q in the Farpoint episode is echoed by Cartmen many years later in the Go God Go episode of South Park when his present/future self calls his pre-frozen past self and tries to convince his past self not to freeze himself in an attempt to not have to wait 3 months for the Nintendo Wii. The Future/Present Cartman with the broader perspective tries to warn the past Cartman that the plan will fail, Past Cartman doesn't believe him, not having lived the failure of the experience yet and hangs up on Future/Present Cartman to which the Future/Present Cartmen exclaims, "I hate that guy."
In an overly circuitous manner, Q always revealed something in his visits whether it was a lifeform being abused by the Farpoint people or the coming menace of the Borg. Probably my favorite Q episode is where he sends Picard back to before he got an artificial heart even though it was more or less a Wonderful Life redux. Picard's disdain for Q was his own disdain for himself.
