Man, season 1 of TNG is not so good. Season 2 is an improvement. In fact, I actually had to pick my favorite from a handful of episodes.
But without a doubt The Measure of a Man has got to be my favorite season 2 episode, and I honestly think it is a good episode of Star Trek in general.
There's conflict between crewmembers, something that just didn't happen in season 1. Sure, it is a setup but Riker has to do his best to prove that his friend is just a piece of equipment. Not only that, but that Starfleet can just rip apart Data and study him in any way that they want.
