For 100 episodes sitcom, it needed a bit larger cast with a few more plotlines. This is why there was some irrelevant guests episodes in the middle parts. After these parts, there was also a weird shift happening. They removed the canned laughter and promptly replaced the mother fairy with a grandmother with no valid explanation. The character replacement wasn't good and messed up the dynamic with the fairies since the grandmother had the opposite personality. Some other characters also promptly disappeared but with no replacement. Most of the material involving the younger cast members was mostly bad, however, the rest managed to make up for that. On the bright side, the twin brothers, fairies and Tae Hee had a good dynamic going on. Some running jokes were pretty decent. Cha In Pyo and Hwang Woo Seul Hye were a great choice to play their respective characters. The wrap up could've been better but it was decent as is.
