I think it's fair to say i'm a traditionalist, which pretty much means i'm stubbornly of the opinion that Star Trek worked best in its original sixties format whether that may be style, colour, dramatic storylines, choice of music, etc. and even down to the special effects - well certainly those relating to the look of the Enterprise. True, the Next Generation's effects were far more elaborate and fancy, but for me their Enterprise never really had the kind of gravitas afforded it, it was so wrapped up in effects, almost to the point of appearing just a touch cartoonish (in my opinion). Maybe this is the reason i felt a little wary of the new remastered version of the original series, especially considering many the old effects had been replaced by more up to date technology. I really needn't have worried, however, because these new features only seem to enhance what the original effects could only have dreamed of, because ultimately they stay true to the spirit of the original series. The stock scenes of the original series which were repeated time and time again have now given way to fresh more state of the art scenes which are pretty much exclusive to each of the storylines individually. This adds no end to the scope of the show, especially in the episodes where special effects appear prominantly, and it gives Star Trek that extra dimension it could only ever have dreamed of at its sixties outset. Even the music has been re recorded, but again it has been done so with a great deal of love and respect for its original style. In fact the new music aspect is hardly noticeable aside from the fact the music has a much fresher and cleaner feel to it.
Aside from the new effects, the first season of the original Star Trek series is arguably the best in terms of possessing consistently strong storylines (Season two was perhaps the greatest in terms of developing the characterisation more fully). There's a greater attention to detail within the scripts than what was to come later (season three).
Generally this DVD set opens up a whole new dimension to Star Trek without ever jeapodising the original vision of the show. The show has been handled with genuine love and affection by those who have been assigned to work on its upgrade, and also with considerable respect. For that i cannot voice my appreciation enough.
