If the idol actor stigma is what is keeping you from watching He is Psychometric, I really think you should give it a go and decide for yourself if Park JinYoung and Dasom are able to 100% deliver alongside a well-rounded and experienced cast instead of disappearing into the background (obviously I believe they have done an excellent job). There are also quite a few strong anti-heroes in this drama as well, which was an idea that I thoroughly enjoyed because it really brought more humanity to a story that could have been completely fantastical.

He is Psychometric is slow moving and romance based to begin with but speeds up around halfway once the depth of the relationships between all of the characters has been established. It also somehow manages to maintain its emotional depth despite this sudden plot speed increase. Arguably the romance could have been omitted but we would have likely been left with fickle 2D characters who had revenge as motivation and probably also a six-episode intense crime only drama, irrelevant characters and too many plot-holes - which is made abundantly clear in the final episode that this is not the story the writers wanted to tell.

Plot-wise for me it also became a bit too obvious about halfway what was going to happen next EXCEPT there is one question about Sung Mo that maintained the suspense until the very end.

Overall, the cast, plot and music was all delivered solidly, the messages were portrayed clearly and there left a lot of room for insight and personal interpretation. This team delivered a piece of work with a lead cast of anti-heroes which I really loved.
Music-wise – the music fits well with the drama, no complaints here.
There wasn't much I didn't like.
Would I re-watch it? Probably in around 5-6 years when I want to be reminded of just how differently people deal with their emotional scars.
