I've been a Star Trek fan for about 25 years now. Sky One in the UK used to show TNG/VOY/DS9 in order with one episode every day, so I watched all three shows multiple times over the years. So I thought I'd seen every episode of TNG/VOY/DS9.

But I recently read about a TNG episode that I don't recognise at all, "Identity Crisis" from season 4. The plot says it's about Geordi slowly turning into an alien, but I don't remember that at all. It seems like I must have missed this episode despite watching the series multiple times.

Apparently it's a highly rated episode as well.

Crazy that I've never seen this episode or even heard about it until now. Looking forward to watching it.
