@Mallery29:
Only Part 2 is worth anything…Granted, “Four Lights” is epic, but as a two part episode, it pales in comparison to not only Best of Both Worlds, but the Gambit (season 7) is better as a whole than Chain of Command.
I think you’re full of crap… but that is beside the point.
In my view, all two part episodes are (should be seen as) a single entity. The story is not complete in a single episode and they should not be treated in analysis as such.
Since I have seen relatively little DS9/Voyager, I will speak for the better TNG episodes you have neglected:
“Deja Q” - the funniest 45 minutes of Star Trek ever done; Q is stripped of his powers and can only use his sardonic wit as a weapon.
“Darmok” - an all time classic, if not one of the most creative; Darmok and Gelard at Tanagra.
“Time’s Arrow” - Data’s head under San Francisco, Mark Twain and aliens sucking the life force out of people… plus the crew gets to dress up.
“Starship Mine” - A well conceived and unique episode that is very fun to watch; Picard defends his deserted ship against terrorist/mercenaries.
“Frame of Mind” - Perhaps the second best TNG episode; creepy… and certainly wonderful watching Riker go insane.
“Masks” - Data acting strangely is always fun, but especially with multiple personalities and weird symbols on his forehead.
These are certainly some of the best, though I can proffer some other personal favorites such as “Birthright”, “Sins of the Father”, “Where Silence has Lease”, “Eye of the Beholder”, “Conspiracy” and “Booby Trap”, just to name a few.
