Well, no points for effort in HTV's handling of the visual effects. Where as CBS Digital would add a little sparkle to their work (fixing continuity errors), HTV seems to be doing the absolute minimum. Not only do the planets look undetailed and fuzzy, but there are some instances where it looks like a solid JPG image. That's when it hit me. A lot of these effects look like they were done without keeping it consistent with the film footage.
Also, I know this was in the original episode, but was it ever explained why the Enterprise's nacelles were offline in almost every shot showing the other ships?
