i must say that seeing the serie's name "gu family book" i didn't expect what i found, i thought it's the average story of a supernatural creature searching for a way to be human and i only watched it because i was running out of dramas to watch, but i was amazed by what i found, at first i was hooked by seo hwa/ wol ryung love story , it was trajic and beautiful and full of emotions and i really wished they were the lead couple , but then kang chi's story began , and again i found myself attracted to the screen by the beauty of the story , and althought i really liked the show , it has it's flaws , first there still many thing that remined unresolved and they basically forgot about the perpose of the story , second even for a fantasy show there's still some things unbeleivable and some times rediculous ( you'll know when you watch it) and it seems that sometimes they make some rules and then drop them whenever they want to , the acting was outstanding and it seems that lee seung gi has grown as an actor and improved himself , suzy as well has a differant kind of caracter in this show who's self dependant , strong and skilled with martial arts and i think she did a great job , even the support cast was really outstanding , music was beautiful ans suites the drama as well , overall it was a good drama to watch and althought it's not perfect it totally worth it
