I will have to say the premiere of ABC's "Duel" was not so good. The pacing was extremely slow, and Mike Greenberg bombed as a host that night. Even I personally got lost what was going on.
However, beginning on the second episode, I really got into the game. Also, the pacing clicked and Greenberg's hosting improved a bit. I also thought it was a nice touch that the finals qualifying format resembles the one for the Tournament of Champions qualifying on "Jeopardy!".
Overall, I liked the show, but I'm not sure if it will be done again. If it is, it should be held in the summer because the ratings weren't too stong.
