The absolute best!! Totally recommend it. Even tough it's R-rated (K16). I started watching it at the age of 11 or 12, and I think that if you've seen movies (or read books) such as Harry Potter, The Hungergames or Divergent. I think it's fine for younger children too (depending on the kid)!
This show has been such a huge part of my life for so long and I completely LOVE it with all my heart.
Please watch it <3
