Do you think 2nd gen is cringy?

3rd and 4th gens are cringy

Not the songs or at least most of them but the styling and effects yes. I started kpop in 2018 so it kinda shocks (not the beast song lol) me and it is kinda cringe but it's the eras.

I still don't get how some of them looks way more outdated than they should be or is it just me??

No as that’s the gen I got into K pop with. It was far better than current gen imo.

I mean all of kpop is cringey to some extent

Maybe yes maybe no

it was more cringey than now but the quality was 10000000000x better

Can't say it much difference with today. I mean like Lisa in Lovesick Girls MV useing a sledgehammer on a car is like.... okey. Sure maybe it's a bit more "mature" and "main stream" today, but not that big difference.

Nope, they've got heaps of good music too

Extremely. Far more than 3rd or 4th gen ever was.
