Yes. One of my favorite YouTube reaction channels is Addie Reacts, where she has pretty positive reactions to older media and doesn't judge it by the standards of the present. She came out of the Christopher Reeve Superman movies with a huge crush on Christopher Reeve. She's currently going through the Sean Connery Bond films from the 1960s and she's genuinely enjoying them. Her enthusiasm if infectious.And a lot of "reaction" shtick—like, I suspect, whatever started this thread—is acting like you're smugly superior to what you're watching.** (Thankfully, there's plenty of more wholesome, open-minded reaction content out there, which is why this thread confuses me a bit.)
"The Menagerie" was pretty exceptional for the time, because it gave the Star Trek Universe a past.But the scope of "The Menagerie", behind the scenes, is genuinely innovative. At the time, so young in the Trek universe's run, with no past apart from only Kirk episodes and how many of the audience believed that the Pike material was prepared specially for this 2-parter at the time, it was very novel. It was also as novel to see "past lore" given a glance, as well as a novel way to cut costs as Trek, up to this point, was the most expensive thing ever made by the studio, complete with two pilots and all, so why not chuck 'em in?
Even though "The Cage" had been made just three years before, it genuinely looked like it belonged to an earlier era than TOS, looking more like Forbidden Planet than a modern production. It was easy to believe we were seeing a mission from 13 years before. "The Menagerie" established the Enterprise as a ship with history, with a Captain and a crew who preceded Kirk taking over. And unless I'm forgetting something, it was the first episode that established that Vulcans were longer-lived than humans, with the Spock of 13 years before looking not too much younger than the Spock of the present day.
Suddenly, the universe of Star Trek seemed like a place with real history, and that gave the show a verisimilitude that it might not have had otherwise.
