Okay so let's be honest it was quite unique till episode 14
There are some majoe flaws in this drama
But still it keeps us engaged throughout the 16 episodes
Acting 10/10 by each and every characters
Music 9/10 especially the ost
Cinematography 8/10 some shots where brilliant but at the same time some scene where underwhelming
Editing was not up to the mark
Writing it was good in the scientific and physics perspective also to the quotes at the beginning of every episode plays the major role
But at the same time writer also messed up a lot of things to be more precise let's say 70% writing was good but at the same time it was 30% was bad
Even though there are so many flaws this show kept me invested from the beginning till the end and I enjoyed
In short it's a time travel mess and if you want to enjoy this show just don't search for logic because at the end it is a drama

In one line this show is a sci fi thriller which gets converted into a messed up melodramatic love story by the end and I am seriously confused should I recommend this or not because even if I enjoyed this show everyone does not have a same taste like me so watch at your own risk
