This is a slow read, not helped by me having a cold the past few days.
What is unmistakable, though, is seeing how much real thought went into all aspects of this film. It's also interesting to note that some of the criticisms aimed at the finished film were genuine concerns of the creative team throughout production. It's a pity they weren't able to find solutions to those issues much earlier.
I thinks that's the interesting thing...they had a lot of solutions, right down the the cast going off and making up their own scenes (that's how it came over later in the book) just no time to get them into the theatrical version.
It's also a question of tastes (not everyone agrees with the criticisms after all) and when the film was being made, no one knew sci fi film was going down the action heavy route it eventually does (production technically predates even the first Star wars, let alone stuff like Alien)
The Motion Picture is more a descendent of hard sci fi than action space opera. It's a different path. That detailed feel is something that goes away later.
After reading that book I do like wondering how much of that original warp core is left inside voyager.
