Firstly, I have to admit: I LOVE mystery/detective dramas. Especially Jdramas of them.
Subete ga F ni Naru was a gem for me this year- it was a compelling watch, and genuinely, every episode had something a little different to offer.

The story was well though out and well paced- if a bit odd at times. The promo photo had me expecting something QUITE different, but it was still a satisfying show to watch, with a romantic plot that was nicely subtle. The relationship between the characters was great, but I felt some of the supporting characters were not well rounded and had very little to offer to the plot at times. I personally think a season two would help sort that out!

The cast played their parts- especially the leads- very well. Moe and Saikawa were a brilliant duo, and I loved their camaraderie. My only issue, is as stated before, some of the cast were under- utilised.

I loved the theme song! It was the only music I really remember, but none of the background music was out of place, so no complaints there.

I doubt I will watch this drama again- at least not for a long time. I am still hoping for a season two to iron out all the niggling questions I still have however! (Much like Hard Nut!)

Overall, it was a great drama. I gave it a nine out of ten because of the loose ending. I still think there should've been at least a bit more to this series- another episode perhaps? It was a nice surprise to me as to how good of a series it was.

I thoroughly recommend Subete ga F ni Naru- its biggest failing is that it ended. :'(

If you're thinking about watching it, or even just bored, do it. I did and it was totally worth it, don't let anything detour you.

Overall: 8.5. Good mystery's and murder's, great geniuses that make you want to be a genius (almost in a sherlock style, but softer.... much softer), and agonizingly wonderfully slow relationship development (this is great because although a lot of people want a quick romance development, going slow makes it even sweeter in this case. It really portrays how much the two mains love each other even before they really discover they are "in" love with each other.)
The main plot is very...clever, brilliant, almost to an unrealistic sense... but still very good. (Perspicacious, would be the vocaby world to describe it.)
(It probably, truth be told, is an 8, but I really enjoyed this drama and so, even though I try (key word try) to be a tough rater, I give it an extra .5)
= Definitely a watch, even if its just an episode on a whim :)

The opening scene hooks you. Your introduced to the show with a blank scene; you know nothing. Not whats going on, not what it means, and not why it would be used as the prized opening scene in a drama. This absence of knowledge makes it a great start. (Honestly I watched this on a whim, and was hooked in the first minute. Plus the hint of romance totally did it for me.)
And then, your introduced to the seemingly main plot of the show, two geniuses solving impossible murder cases, and a small dash of romance. Personally, the romance drew me in more than the crimes themselves, figuring out the relationship between the two mains was definitely a great plot line (though they could've execrated it a little more, but of course, in traditional JDrama fashion they made it slow as hell. Anyway... back to the main point(s):

Story: The main plot lines, both the mystery and relationship, were well planned and well executed. I gave the story an 8.5 because, like most dramas with varying plots, there was definitely room for improvement. One being they totally could've lengthened the romance plot, and intertwined it with the main mystery plot in a much better fashion, but it was exhilarating and agonizingly good they way it was officially done.

Acting: Overall the acting was pretty darn good. I really liked the main actress, and although her acting wasn't perfect, it was almost there. As far as the main actor... I really liked him too, he was really cute, very good at being both lively and brooding at the same time (I know, I don't know how it's possible but he did it and he made it look damn adorable), but I feel there were definite moments that his acting could've been better during the more serious scenes. I do acknowledge the fact that his role was harder the main actresses though. Everyone else was more of a side character and I can't really judge them, first of all they're either to small to have a difficult part, or are just not super good/professional actors so... (I mean that in the nicest way possible...).

Music: There wasn't much music in this particular drama, but I really enjoyed the opening and ending credits songs. Also they made good use of suspenseful and creepy music when the need showed itself so... B+...(more like a B, but I really liked the opening song so..... + for personal preference!!!!)

Rewatch Value:
Ok, so I would probably re-watch this if it was on in the living room or something, but I'm not sure if I would ever intentionally re-watch start to finish.
Reason 1: It's a mystery drama. And I'm really good at remembering plot lines and endings, so, I would probably remember who killed who and how, in order for me to completely re-watch it, I would have to wait a couple of years. That's basically the only reason...
