Favorite Nostalgia shows and why

So I'm gen Z and I was reflecting on how I missed out on a lot of Gen Z nostalgia shows (i.e Teen Titans, TAWOG, Adventure Time etc) due to my lack of access to cable. I've been questioning how many are worth watching, I'm also curious about other gens nostalgia as well because I enjoy things like DS9 and the OG Black Mirror, I also think its generally good to consume both older and newer media. So with as little spoilers as possible hit me with your best and why it's your best.
