No.Let me rephrase it.
One of the most interesting premises in 2023...

Lets break it into some smaller parts.

Music:Although i finished it few minutes ago,honestly i don't remember any piece of music,melody or tune.I wasn't distracted by it but i never felt that added something to the Drama.Dull and totally forgettable.

Production was excellent.The direction always gave the right mysterious and suspenseful vibes.Great camera use, too.But what really stands out is the gorgeous,stunning and absolutely brilliant cinematography.The use of lights and shadows,the color tones,everything was such a treat!

Cast & Acting.Iam not really sure how i feel about it.I always have faith in Korean actors to deliver, so i can't say acting failed me here.But it wasn't super exciting and memorable eiher.Sometimes felt flat but not in any case bad.

Story/plot & characters:

This is not a 10.Definitely not.Is not a 9 either.Not to me.
But is a solid 8 and i will explain why.

Ok first of all i have to warn you.
If you are like me who absolutely loves psychological thrillers,heavy plot,dark and twisted story , deep, troubled and insane characters...this is not the case.If you are looking for something like this do not have your hopes high because you will be disappointed.

I started this because iam a crazy fan of Time Travel,Mystery,Serial killers and any dark story.
After finishing it(just a while ago)i can say this was the most fluffy,sweet and adorable crime/mystery/murder Drama i have ever watched.
For my taste this is not good!Lol.But i loved My Perfect Stranger,kept my interest all the way and never bored me,although it was nothing like i was expecting before i started it.

Iam aware the Time Travel type Drama is not an easy theme to create and develop a fully satisfying story.There are always plot holes,issues with the time line and all these.Iam too familiar so i can't judge it harshly.
But the story is engaging,making you dive into it really easy and fast.It is very clear why the time travel happens,why our male lead returned to the past and how the female lead got involved into this too.In other words is an easy to follow story and as ive wrote in another related review,i was too happy the time travel device was a car.(yes ofc Back to the Future huge fan here!)
I don't want to give away any spoilers.Is the kind of series you really have to go blindly into.The main question here is of course "who is the murderer"

So from episode 1 until the very late episodes the writer have you guessing and squishing your brains and making you losing your sleep on your trying to figure out who the hell done those murders!I was like this for many eps in a row.And then i tried to focus on the motive and not the actual killer.And then i gave up.Lmao.Iam too stubborn to quit but i was frustrated for not been able to solve the puzzle.And this is the main reason this drama is so good and the writer did an excellent job to make a story so interesting and enjoyable at the same time.

So why i gave an 8 instead of a perfect 10 or a great 9?
This Drama can easily be somewhere between 7 to 10 depending on what you expect,how much you like time travel series,how heavy you want the plot,if you pay attention to the details,if you love airtight stories and so many other variables.

My Perfect Stranger is the kind of drama which has an interesting story to tell.Is all about the story.Actually it has nothing to do with the characters,as all of them are here to tell and present the story itself.So the characters are the narrative tools.
And this is one of the main reasons i deducted points and gave an 8.
There is no depth or any kind of character development.They are ordinary,simple people living ordinary simple life.Yes of course our main leads are smart and brave enough to get themselves into this mess,but you know, iam sure we all are looking for that one magnificent character to instantly fall inlove with!Here i couldn't find the One!

The only one that got my attention and if i had to choose my fave, would be her,Go Mi Sook.She was evil in her way and the actress who portrayed her did an excellent job.I wish she had more screen time,though.

Iam taking about the characters but i haven't mentioned the main villain yet...No i will not reveal his/her identity,of course not.But i was disappointed by this char as i have never before with any other crime drama.Not only because he/she wasn't the psycho i wanted to see(hahaha)but mostly because the reason/motive for all the murders was such a bummer!Again i cannot say more to spoil anything,iam just justifying my rate.At the end you will be left with few unanswered questions,but is ok i guess.

All in all is a good drama.It has a bit of everything.Time travel,mystery,serial killings,heart warming family bonds,friendships and a sweet romance which doesn't overlap the story.
It wasn't what i wanted to watch when i started it but i never,not once, thought to drop it.
Go for it,it has many to offer if you like to watch something different.
