It would be away to do a new show while also tying it to the success of the new movie. I could see them doing 3 different things with a Pike series.
1 His adventures as the captain of the Enterprise.
In principle, I'd find it interesting but... he was captain of the Enterprise for about 10 minutes, then was captured by Nero, released and relieved, and was captain of the Enterprise again when Kirk was demoted but never commanded her again.
What adventures would you show ?
