Story - It would have been great if the storyline shows both Rembrary / Woo Yeon Woo characters. That way, it would gave
Kim Min Gue some opportunity to be a versatile actor and demonstrate 2 different sides of characteristics. Instead, it was mostly Rembrary getting viral and more popular due to the wrong reasons. For a person came from a different planet, it would have been a challenge for him in terms on the language and mostly other stuff that Earth people live through. They also went overboard with the poison victims plot.

Acting/Cast - Acting is there but just not impressive.

Music - Not really paying much attention on the music played.

Rewatch Values - I dont think it worth rewatch. I managed to finish watching it all but by splitting half episode per day.
