The best hit

Very bad script, I don't know who could write such nonsense, a father goes into the future and falls in love with his son's sympathy?! Apparently the screenwriter of this nebula has a similar fantasy as soon as he wrote something like this. Acting very superficial and unconvincing. The main character is knocked down by some grimaces that do not make him a cool character but a mentally retarded person. Wasting time watching this nonsense ...

This drama was perfect from the beginning until ML falls for FL. The ML character was funny , naughty n well written. Min Jae is always a sweetheart.he is just best in everything. All other characters well written and cameos were eye candies.. until ML falls in love with FL..from there on it was pure cringe. The ML has zero affection towards Min Jae even after knowing he is his son + he falls in love with his sons love + the ML and FL total lack of chemistry. The FL giving zero f's about Minjae's feelings despite him being for her since childhood and always open about his feelings - like don't fall in love with him i understand but having zero courtesy and flirting with another guy in front of him. I plain hated the FL . 1st time in Kdrama history i absolutely despised the ML and FL romance. N just forwarded all ML +FL scenes n watched the story of other characters.

Good drama to watch if you like comedy drama and it also about struggling for your dream.

This was very much a feel good, happy-type of series to watch. I am a huge Yoon Shi-Yoon fan, and he was my main reason for watching, which was good because this series revolves around him. I really liked the music and the character dynamics, which were the very heart of this show. The time travel part is really just the premise, this is more of a slice of life type of show with a bit of romance towards the end. The time travel part was never really explained, and it wasn't the main focus of the story, but it didn't really matter to me and I very much enjoyed watching Mr. Thumbs Up on his journey of self discovery.

I went into this show with zero expectations. The first episode was good but a bit weird, but after that this show was gorgeous and i didn't want it to end. It has a perfect mix of quirky, funny, sad, serious... all mixed in with some serious eye candy. (Yoon Shi-swoon!). A great soundtrack too, which i found on Spotify.

I rarely rate a 10/10, but something about this did it for me. I wish the President Jay1 had a worse ending, but i totally recommend watching this. Do it, you won't regret it, even just for the spot on 80s/90s dancing, video clips and tunes.
