I don't see much of a reason to be worried, either. While it's unfortunate that Doug Drexler is out, there are still quite a few talented people involved. I like most of what I've seen so far, even some of the recent changes like the less 50s-ish logo.
Just yesterday, I looked at all the audition tapes for the lead role and was surprised to find that almost all of them seemed quite professional and that there were actually several that I liked. I would be more than fine if Zicree managed to match the quality of his "Star Trek Phase 2" episode "World Enough and Time", and that had some pretty awful acting. "Space Command" already promises better acting and production values than that.
