What is wrong with today's Zombies?

For context, I stopped buying cod games since black ops 3 (exception is Cold war). I have felt the franchise was straying too far from what it was originally meant to be. In addition the games are the same old same old now.

I've recently been seeing gameplay shorts or videos from anything on older black ops games to the newest one. And one thing I have concluded is at least with my stubborn nostalgia for the old games is that... The newer cod zombies, since that awful excuse of a game WW2 came out, isn't the same experience anymore and has been dumbed down for little skill or care to actually play a challengeing game of survival and/or EE completetion.

In black ops 6 I heard that you could just give yourself weapons before being dropped into the zombies map via (your exfil vehicle). Which i guess renders map based weapons and the mystery box completely pointless.

So I have a question. What the flying f*** is this new zombies. And please, I'm not trynna upset people. But as someone who hasn't played the newer zombies, what could possibly beat out the og zombies experience with the new one?
