The plot of this drama is definitely unique for a RC and I enjoyed the general premise of going back in time to try and fix your mistakes to get a different outcome. What I really didn't like was how long it took Ken to actually speak his feelings to Rei, which made the drama drag. The first few episodes were good, the middle ones were hit or miss, and the very last episode or two were good again. The acting by all parties was ok. Ken's character was a bit flat and uninteresting. Rei's character I enjoyed and I thought her acting was spot on. All their friends had fun characters that added a lot to the story and without them it wouldn't have been as good. Tada-san's character was also a bit flat as well and at first I didn't really care for it at all. Music- I loved the soundtrack of this drama and the ending ost was great. I'm going to have to see if I can dig up some sheet music for the songs as I liked them so much. Rewatch value- is so, so as although I may rewatch sometime I think I would skip a few of the middle episodes since now that I know the plot it wouldn't be all that detrimental.
