Having been released in 1990, some may find the subject matter dated. "Been there, seen that." In addition, this movie may not appeal to someone that does not want to be reminded of unpleasant facts. For instance, there is a line in the movie that goes something like, 'we took a bite from the apple and now won't be happy until we have destroyed every part of paradise.'
It seems at the start of this film, that it is going to be about an adventure in the jungle. An adventure like Indiana Jones or something like that. But the real adventure is in the transformation that takes place int the central character's life.
It is a slow-paced movie, but riveting. Slow-paced in a dreamlike way. Sort of like having a fever and being conscious of what's going on around you but it all seems like a dream. (The previous is a very inadequate description, but the best I can do with the words I have.)
But it wasn't all wonderful, and there may be things that will stand out so much, many won't be able to look past them to enjoy the film.
There are disjointed parts, unexplained occurrences, and some glaring inconsistencies. The one that bothered me most was hair. These people were out in the Amazon jungle, hundreds of miles from anything resembling a city, yet the main characters hair was always salon cut. One of the girls started out with short hair in Finland, and her hair length never changed, even when they were living in what was little more than a slave labor camp. It would have been different if their hair looked choppy or like bed-head, but wherever they were or no matter how much time passed, everyone's hair always looked freshly cut. For the detail inclined, this will be distracting.
Despite any negatives listed here, I truly enjoyed this film.
