To tell you the truth, I wasn't so convinced at the introductory phase; the screenplay felt repetitive, the story wasn't making any visible advancement either, and the characters too were struggling to establish their prominence. Finally, after several episodes (Episode four onwards); the show eventually began showing developments and from thereon it slowly grew on me. I feel it's the 'drama' that weaved its magic thus assisting in making things better!
Now, if you cut out the dramatic portion; all you're left with is an investigative piece that lacks a certain ingenuity, a certain sharpness. Do not get me wrong, it does work out in the grand scheme of things but I think, further stability, particularly at its foundational level was an indispensable requirement rather than a nonessential element of convenience.
P. S. Episode Six (RPG) was my favorite, Afran Nisho killed it.
