Your favorite “Star Trek” episode?

I’m prompted to ask because I noticed that today is the anniversary of the first airing of one of my own favorites.

“Blink of an Eye,” an episode of “Star Trek: Voyager,” aired on this date in 2000.

I haven’t actually ranked all of the shows. But I suspect I would place it in my top 10, all of the “ST” series included.

So anyway…do you have a personal fave?
