Is there a manga/manhwa/manhua with a perfect 10 star rating at all??

That's impossible so no

I know I was just curious..there's always some haters saying a series is mid..:(

There are some, but they only have 1 or 2 people rating it:

I also know some with a rating of 0.0

No but Sangyang:The Wanderer should be a 10 star
