Idk if this is based off of a webtoon or manga, so maybe they were trying to stick to a certain story?

Season 1 was great. Great casting, acting and story. Little to no skips. Season 2 they gut the acting and replace some characters. Story was mid. Acting was average to above average. A lot of skips or watching with the speed at 2x.

Season 3. The 2 kids were the most entertaining and well written, probably by accident. Go Min Si and Lee Do Hyun were amazing. Song Kang with another robot performance. Every scene he was in whether he was angry, happy, sad or trying to be funny.....just a straight face almost like he was confused.

If you were expecting redemption from how bad season 2 was, you'll be disappointed. Only giving it a 7 because Go Min Si and Lee Do Hyun were that good.
