I really think that episodes 1 to 4 are 10 rating. Park Sao Ham is just amazing and deserves an award. Especially for the first four episodes. Park Jae Chan is very good in the first 4 episodes too, but I feel he gets better, and his character is more likeable in the last 4 episodes. Episodes 5 and 6 are transition episodes that could have been better. PJC character loses something in episodes 5 and 6 but gains some more depth in 7 and 8. The ending is somewhat anti climatic for me. Could have been better. For sure the first four episodes were the most enjoyable series I've ever seen. It was fresh, quirky and very engaging for me. All of the support characters were very strong especially Song gi oh. congrats for a great series. Make more like this!
