I guess i am also one of the very few who cannot rave about this show and this review will not be liked by most of the current (young) audiences but well since i watched i will provide my thoughts

I was attracted by clips of first few episodes and story line thinking it will be "we. will cross all hurdles including time and space" type of love story which i am up for watching anytime but i was disappointed big time.
First two episodes was gripping. First wave of disappointment came in when there was fire in Im Sol's house . What was it ! why that sequence which did not make sense and its utterly annoying to see such stupidity. Its not comedy if it does not fit into the flow of the sequence. Randomly these sequences are integrated. There are some comic scenes which is really good but most just falls flat and importantly it does not contribute to the story in any way.

But what really doused my interest is ML already liking her and with just one look and no interaction in original timeline .Liking her to the point where he cares nothing but her. That just destroyed the premise for me .
ML cares about swimming for first few episodes then he doesnt give a damn. After that its like a list of cute scenes or crying scenes but really what is their relationship if we dont see them sit and talk and discuss other than saying they are happy !. He was a student who worked hard for it and now he is just a romantic goof .
If only their relationship was built with more substance where she comes back to save him , bcs she saw him as a person who gave back her spirit of life but then slowly turns into something more and the same with him but no.. it all stays in a very superficial level.
Even FL does not show any maturity when she is supposed to be 34 year old in the body of 20 year old and that too for a person who has gone through so much and when she remembers all of that! Being full of life is not same as acting all teenage like!

Psycho story line is a mess as well. A criminal attacked police officers and how come he is still roaming around and police officers are listening to a teenage girl what to do!! No wonder they could not keep a criminal in hand cuffs in place lol.
And then later he also manages to come to a 5 star hotel to attack the ML. wow! thats hell of a security and policy system this world has!

Same with SML and ML's friend . ML did not even know where his friend lived. And SML one day became buddies with them and enjoying in the beach ( another beach scene cliche thats a must i suppose) when he had his own gang which disappeared ?
Point is none of this characters or the relationship is built up on a solid base that you care about them (Cant help but think of SOOD here)

Only good thing is the leads and the actors who do have a good comic timing ( but sadly all are over the top or out of place)

This plot had the potential to be as good as Someday or one day. Sigh ..

PS : i am still giving ratings more than what i think it deserves
