Does TNG hold up 40 years later?

I can’t believe it’s been almost 40 years, but wow. I first watched TNG as a child with my mom when it first came out. Great memories, but I was a little too young to really get it. I re-watched a few episodes in the mid 2000s as an adult with my roommate until he passed away, then I stopped. As an adult, I had a totally different understanding of it, more from a moral point of view. I thought it was amazing. I’m thinking of watching the whole series. Did it hold up? Or am I setting myself up for a big disappointment? Philosophically, was it actually deep or was I just impressed because I was young and dumb?
