If you liked the original Dragon Quest Adventure of Dai anime or manga, it has a very similar feel to that.
If you are familiar with Dai no Daibouken this series fleshes out many of the events that were only briefly hinted at in Dai no Daibouken: How did Avan learn the Avan Strash? How did Maam's parents, Roka and Leira, get together? How did they meet Matoriv? How did grandpa Brass wind up on Dremline Island? What was life in the subterranean castle really like for baby Hyunkel? How exactly did Avan defeat the demon king?
If you are not familiar with Dai no Daibouken, the story still holds up. The art is modern compared to the old very 90s-looking Dai story and this series tries a bit harder to incorporate Dragon Quest game content (bad guys and spells)... but the story is at it's heart a wholesome story that follows the same tropes that all DQ stories are known for (good guys win against the bad guys).
Right now there are only 8 English chapters out. So it's not terribly long to give it a shot. If by Chapter 8 you don't like it, you probably won't like the series as a whole.
