You misundstand me. I’m probably one of Enterprise’s biggest fans. It’s just not what I’d recommend for someone getting into Star Trek. It’s tone is different, and the roots of the franchise aren’t easy to see if you don’t know to look for them. I wouldn’t recommend Discovery as a first show for the same reason. Strange New Worlds though is an excellent option.
I’ve actually personally been getting a friend into Star Trek through Lower Decks and DS9. Once she was hooked, telling her there was a Lower Decks crossover in SNW got her onboard there as well. Now we’re kind of watching everything simultaneously lol
Strange New Worlds, despite being a prequel, is a great place to start. Deep Space 9 is also really good for learning about Star Trek, and it’s probably the best written overall. You could also watch a Best of the Next Generation marathon. I’d recommend that over watching the whole thing, because TNG really shows it’s age sometimes.
The most important thing to remember is that most Star Trek shows take a little while to get off the ground. They usually find their feet around season 3 (that’s when Riker grew his beard).
