Last week I watched a bunch of TNG episodes from the 1st season. There were a few decent ones, but most of them were just awful. Worse than I remember.
"The Naked Now", (Episode 3, the one immediately following the 2 part pilot, "Encounter at Farpoint") was where all the crew members, including Data, got intoxicated with some space virus. Data and Tasha Yar slept together and Wesley acted like an idiot. The plot was intentionally copied from a TOS episode ("The Naked Time").
The scene where Tasha seduces Data is cringe inducing.
