A review of this show is not entirely possible since at it's core it was unfinished product intended to last for far more than one half (plus) season, but I can't help myself.
I first saw the show when it originally aired (with The Trainjob) and followed it as best I could - with FOX moving it around both on the night and time it aired as well as preempting episodes for sporting events (that they KNEW were going to happen... rage), but I still fell in love.
The first scene that made me fall in love was of them out in space and the distinct lack of sound that was present in the space portions. I did not care at that point who the crew were, why they were doing what they did, or what they were doing. I just wanted to see how science fact this show remained.
Obviously it didn't really stick to science fact, but as I continued to watch, as with previous Joss shows (which I did not know were made by him at the time) I fell in love with the writing.
Not the specific stories, or depth (or lack of depth), but the words themselves. Joss has a knack for writing people that sound both real and "written" at the same time. That perfect amalgam of what sounds like it should with what sounds like we want it to (if we had time to write our own dialogue in real life conversations). The amount of quotable lines and hilarious, touching, dramatic, and horrifying script that comes from each character was that wonderful blend that makes a Joss [Whedon] show so good.
The special effects do not stand the test of time (I just re-watched it recently), even tho for a tv show - at the time - they were pretty good. Some of the western themes get over done and make it enter an uncanny valley of sorts for a genre mish-mash. And the stories seem at some times rushed and at others too slow. But overall, taken as one complete whole, it "had potential".
That is a phrase often used for this show to glorify it as the greatest thing since we broke orbit (to use a space-y euphemism), but I am not saying it was the greatest, just that people that enjoy sci-fi shows should give it a chance.
I do not mean just watch the episodes, but try to take yourself out of the mindset of everyone hyping the show up since it's cancellation and just try to enjoy each episode and the characters in it.
I am not much for review "scores", but I would say see it at least once.
