It's interesting. 
If you are a fan of action-comedy it might just around your corner. 
One thing that was a major con for me is the stupidity. 
It feels like MC is stupid but compared to everyone else he is smart. Which implies that author needed to make the whole world stupid just to make this story. 
Barbarians are around 60-80 IQ
Humans(and elves) are around 80-100 IQ
I know it's not the perfect metric but it roughly explains how it feels. Also MC isn't 100 iq, he is around 90-95. A bit dumb and goofy.
