The only thing I absolutely hate about this show is that Meliodas is such a gross pervert. You can't watch the show for 5 minutes without Meliodas looking up Elizabeth's skirt.
It's a good show if you don't mind overpowered MCs. And this guy right here is seriously overpowered. No one should be able to wipe an entire city along with the hill it's on just because they got angry.
And then there's Elizabeth. She's your standard female anime protagonist. She gets in trouble and then Meliodas has to come and save her. Although, she does get an awesome power at the end of the show and ends up saving about half the population of her kingdom.
The plot is good and the six other sins are pretty powerful. That said, this show could have been a lot better than this.
