Jacqui and I watched Commanche Moon yesterday. I simply couldn't connect with any of the characters at all. I saw it as a typical sequel not worth watching the first time, let alone a second.

All those Star Trek wannabees are the same. No other characters can fill Spok's shoes, or McCoy's or Scotty's.
You must have a good story line, but strong characters are what make or break the whole thing.
