Big fan of Caesar Samayoa -- think he was quite strong here, and he was very strong as Juan Peron in Evita at A.R.T./STC as well. But I think at least some of the Amigos subplots need to go. Particularly the "divorced dad looking for love" subplot. I also wasn't entirely sure where the "Ashley doesn't know what life is without dance" plot was going -- I would much rather have spent that time learning more about each of the group members, or even the relationship between Mel and Ashley.
IMO, some of the time spent on some of the secondary characters (the parents, Dr. Amigo, Ashley) diminishes from the time we could be spending with the main seven group members. I was most invested in their stories -- and left the show hoping those storylines would be fleshed out a little more. Mel's storyline felt particularly incomplete.
