I finally got around to watching the last 2 episodes. I decided not to watch any of the earlier episodes, so just the final 6.
I do not think I could watch a 90 minute show of Kenichi. I thought he was very good, but to sit through a long show it would not be my thing.
The singers were all ok. I like the magician, but I doubt he could do a 90 minute show now. I was impressed that he is only 17 and I think he could do well in the long run.
None of the finalists really blew me away, of course I did not watch them over and over again for the summer, just the last 2 shows.
