Clearly most people reviewing this have not taken LSD in significant amounts.

I have. And the movie is the epitome of a bad trip which could easily happen. You see, human society is the convergence of many people that have egoistical concerns. It's amazing that we manage to keep this world together despite all the differences. A lot of it is due to law and moral values that are based in major religions but not everything. There is a social contract every step of the way which is crucial for the world to work.
LSD is a dissociative. At certain concentration it makes your ego separate from your perception of reality and throws in a decent amount of visual and audial hallucinations. You no longer are you and the world is no longer what it seemed to be. A very real notion that the world might never be the same again visits you time and time again. This can be a very positive introspective experience where you realize the socially acceptable limits of your ego but it can also be a frightening one if you have not been the best person you are. We live in a "me, me, me" age where over the top exhibitionism of our accomplishments or just vanity is looked up upon (thanks to popular media for that). LSD cuts right through this mirage. And the movie shows just how horrible it might be if every single person realized this at once, in fear of it forever staying the same. A true nightmare, if you will.
Overall, I think that it has both artistic and real-life value but it succeeds in only portraying the negative side of dissociative use. To put things into perspective, there should be a diametrically opposite movie that would show the other side of the coin (inherently positive experience) and, thus, the waking life of our realities would be smack in the middle.
