Perhaps I can give a somewhat informed guideline for deciding against the purchase. Devil's advocate. Whatever.
When I myself am riding, I'm not at all an EC enthusiast technique-wise, although I do love to watch it.
I purchased it at around the time it came out, so I don't really know what the extras are that we get besides the 7-minute video.
This may be kind of obvious, but I didn't really think it through, myself. The content is 7 minutes of what is actually much less than that 7 minutes of real riding time. The Red One camera records a purported (from a quick Google search) 120 fps. I'm being very rough with calculations, but I'm just trying to get a point across. Please forgive anything terribly fallacious; not trying to preach that you shouldn't buy the film, but there are things that probably would have made me decide against buying it had I realized them beforehand. Ultimately, that's just me being a college student and not really having my own money though. The footage really is beautiful. You can find the trailer if you snoop around on the actual site or search youtube. Just keep in mind that they have a few full-speed shots in the trailer, but the entirety of the actual film is played slo-mo.
Let's say that they want to take advantage of the 120 frames/sec by replaying the footage at a more human-readable 30 fps... In the end, you're showing only 1/4 of the actual riding time, turning out to be under 2 minutes.
I would have been happier if we had more footage (perhaps just make available all the raw footage as well) AND if we had access to all the same footage played at normal speed. Guess you could tell me to not be lazy and convert it myself, but I'm lazy. :)
