Thanks for the comments guys.
Poke: very good point. I suppose the script would be boring to read as it stands right now. Since I did/will shoot this I didn't include much detail about the visuals, which incidentally, comprise almost the entire narrative (intentionally).
Confusion isn't a good sign! I think it makes more sense when you see it visually though. It wasn't put together for the visuals per se (though I wanted to include the oportunity to utilize some local terrain which absolutely rocks). I'm glad the forshadowing didn't completely give away the intent of the script. I felt like some forshadowing was necessary, but I DON'T want to make the final intent obvious that early.
Your comment about the end was very useful. Thanks! I really need to make it obvious that the end of the script is near. As it stands right now it's sort of semi-random - though perhaps reaching the top is a near enough subltety? Perhaps a stronger forshadowing of the final destination? Hmm, definitely something to ponder!
Spatula: Thanks for the comments

. Actually I didn't (consciously) intend to imply anything about religion (though I'm glad the metaphor was abstract enough to allow personal interpretation! That was my hope!). As a metaphor I wanted to leave the exact interpretation up to the individual while providing the necessary thought provoking atmosphere.
I did have several general themes on my mind when I wrote the script though. Actually I was originally inspired by Plato's "Allegory of the Cave." The script eventually moved in its own direction but the cave influence can still be seen

. I wanted to question what we commonly percieve as reality. We often live in a dream world of our own creating - whether that be politics, religion, a personal problem which seems unconquerable etc. A prison of the mind so to speak.
The transition from darkness to light was meant to parallel the above as a metaphor for enlightenment (and thus the subsequent pain in the process). The ascent can fit pretty much in the same catagory - the struggles, the pain, the ease of giving up on the way to the final destination (a destination which notably the prisoner does not know). And I'll leave the rest up to individual interpretation

(as that, really, is where any power from the script will ultimately lie).
"nice little message short" describes the intent well I think

. I'm really looking to play around with the visuals and I think it will help me become a better filmmaker overall in the process since I get to focus almost entirely on performance and visuals.
Zen: Nope! I'm not familiar with TV from the 60's really

. What show were you thinking of?
As Poke pointed out, the script is nearly 100% visual and I didn't exactly expound upon the visual elements in writing (as I'm shooting it myself). I'm mostly interested in thoughts regarding the flow of the story, etc. I went up and shot most of the footage I need for the short utilizing a skeleton crew and friends. It was useful as it allowed me to play around with a few visual elements and see how they really worked. I do plan on shooting this in a more serious manner later though with real actors etc.
