A pair of teenage friends will try not to be Sherlock Holmes, something they seem to be good at, but it causes them problems. Still, they will find themselves in situations where they will use their great deductive skills nonstop.
If you really like the detective genre, so much so that you've seen countless works, then and only then, this might seem refreshing and like a great piece of work to you.
For the rest of us mere mortals, among whom I count myself, it's a bland work, shoehorned in, with a very large shoe. The script is overly forced, and the characters are so strange that my initial hypothesis was that they might be extraterrestrials.
It does deliver in the visual department, with a more than decent artistic design, where the standout feature is the wide variety of candies, which are relevant to the story.
For me, the result is insufficient because it never quite figures out what type of work it is. It's not teen, it's not detective, it's not romance, it's not drama. It simply isn't.
