Ok.... this drama was at the same time aweSOME and awFUL. Until about episode 16 or so, it was mindblowingly good! The main character is this crazy hero, who is so intelligent that he is practically an alien. And love story is cute, although very expectable. Ok, there were some minor flaws when it comes to the police work (like walking all over the scene of the crime and touching stuff etc.), but you can forgive such flaws, just like the bad acting of most of the foreign actors. The intelligent plot is great to this point, but THEN.... everything changes: 1) Right after they fall in love he just starts behaving like a normal person, thus looses all his charming antisocial features. 2) Then comes the all-tying plot in, and it is so DAMN PREDICTABLE that I couldn't believe that it comes from the same writers as before! 3) Everything becomes one huge ball of clichés, you expect this to happen, then that, and this again, and it all does. Freakingly disappointing! 4) And it starts to draaaaaaaaaaaaaaaaaag... Seriously, from ep. 17 on I felt like watching something in slow motion.... because of the predictable "turns" it was even worse, not just the directing. The pace was totally off. So - while the first arch of this drama was insanely good, the latter was so bad that I really had to force myself to continue watching. Jeez, that was a pain in the butt. The only good news: The last episode improved on that. But the so charmingly outlandish main character was lost on the way. The good part would get a 10 from me, the boring part a 6, thus it ends with an 8. It is still worth watching, though.
