Re: Rewatching Star Trek Enterprise
The only way they could have done a mixed cast reunion movie is by which actors wanted to return. Until then, you don't know who your characters for a story are and have to write something generic. Captain Janeway with First Officer Ezri Dax, and Communications Officer Hoshi Sato might be a result.
And if Bruce Hyde wanted to make one final shot, Kevin Riley could be in the bowling alley.
