Now THIS is a perfect example of a Japanese drama done right. I finished the final episode earlier today, and was very pleased with the ending. Watching this drama was definitely a roller coaster. All the surprises and the twists and turns left me on the edge of my seat throughout the entire ride. The mystery introduced at the very beginning of the 1st episode definitely gave a bit of a feel of how the rest of the drama would play out. It was interesting, compelling and will leave you guessing every episode. The acting was my favorite part. Sakurai Sho did an excellent job in portraying his character with all of his crazy antics and questioning teaching methods, but didn't necessarily outshine the other actors who I thought portrayed their roles just as well. Speaking of which, Kamiki Ryunosuke definitely stuck out to me with his portrayal of Numata Shinichi. I think portraying someone who was as psychologically unstable as that is not an easy task to take on, but I thought he did exceptionally well it portraying his character and was pleasantly surprised with his performance. The music was very fitting for this drama.. Although, being an Arashi fan, I've gotta say I did fall in love with the ending theme "Endless Game"... But I generally tend to like their music, so that wasn't much of a shock to me. Overall I highly, highly recommend this drama. If you like "mystery" type dramas, I suggest you check this out. You won't be disappointed. This drama will keep you guessing every week and the story plot is definitely something to stick around for. It has a very pleasing ending that wraps the drama up nicely and will actually leave you with wanting more episodes. I guess we can only hope for a future special, right?
