Do you like Action-adventure games? Do you like Shadow of the colossus? Dark Souls?
If you like all of the above you'll love it.
The gameplay and world is what holds it up, it's just a fun action-adventure game with a very memorable and fun character/combat system along with it's unique feeling with having pawns (npc's) that make up your party and do things in combat.
Good deal.
Price is certainly in to "why the hell not?" territory especially with GMG discounts.
