When I have to fast forward through spots out of sheer boredom, then I know I haven't seen a good movie. It was just a minute here and there, especially during the first half hour, which as others have noted, is extremely slow and uneventful. I would think that for 99% of the movies we see, the director should realize you're not supposed to turn off or bore the viewer, especially because the director isn't famous, the people aren't very famous, and the event itself is not very famous. I happened to be in Tucson, AZ in November of 1993 for my brother's wedding, and visited Biosphere 2 after the wedding with my sister. We both were fascinated with the whole concept, and indeed, when this documentary focuses on Biosphere 2, it's pretty good. Unfortunately (and incredibly), Biosphere 2 isn't always the primary focus. There's an interesting documentary to be made about Biosphere 2. Sadly, this isn't it.
