You see a lot of criticism of the first season, some of it earned, but let's acknowledge not just the quality of the highlights, but how they occupy a unique position within the TV stories.

1. Patrick Stewart. As ever, without fail, he's number one. He's so good, as the straight captain, or as the guy freaking out Redblock, or adding the comedic flourishes ('Mr Data, step on it' is quality). This is all because Stewart understands both his role and the world he is suddenly inhabiting for a week. Just brilliant.

2. It's a TOS episode. These types of episode mostly only exist in season one. You can criticise its similarity to 'A Piece of the Action', sure, but point is, Next Gen had to have this, and wow did they nail the choice of world to portray. Consider 'A Fistful of Datas': another "let's use a different show's stuff" episode. And it's odd. Sorry to its fans, no doubt it has its moments, but it just is!

3. Not Patrick Stewart. Gates McFadden's best season one show, and arguably top of her whole pile. Tierney is absolute gravy, the effortless chemistry between him and Stewart is chef's kiss stuff, easily top ten guest appearances, probably top 3. You have to mention Spiner, I know we're used to his talents, but are they better utilised than this episode?

4. It introduces the metaphysics of the holodeck. There are reams to be written on this, but consider its place as the prologue to 'Elementary, Dear Data'.

5. Finally, I promise. The Maltese Falcon. It's amazing, and if you're struggling to get why this episode even exists, just go and watch it, I pinky promise.

I could easily bang on to at least 37, I'd love to hear other takes, but wow, sometimes an episode gets you!
