I mean, I respect the hell out of it for basically inventing JRPGs, having great music and art, and some of my favourite series are parodys of it (Earthbound/Mother).
But lord help me, I just cannot get into this series. It's stories and world building suck. It's so very, very chuddy in its values and characters. All about birthright and bloodlines (Something that's putting me off the Zelda and Fire Emblem series too as I get older). It's also got that Square Enix sexism stink that I find myself being less tolerant of the older I get.
Please feel free to roast me for this opinion, it's just my personal preference after all.
If you like the Dragon Quest series I would love to hear why, because I want to like it. Maybe I just haven't played the right one. I've only played 8 to completion on the PS2 back when I was a kid, and I tried the Demo of 11 but wasn't really gelling with them changing the iconic presentation of their battles, if that makes sense (a nitpick, I know)
I tried 11 and at its best I was bored, at it's worst I was actively disliking it. I maybe did like 10 hours because I know how JRPGs can take some time to find their form but Dragon Quest is definitely not my thing
11 is the most beautiful a Dragonquest game has ever looked but the story is fucking whaleshit. I wanted to like it so bad but it's just the most boilerplate a Dregonquest story has been since the first 4
