Welcome to the forum, Ripley.
I have commented on this movie many times here, and even started a thread on it once.
What I feel is most important about the movie is not what it contains, but rather that it may motivate some to question their sense of reality/self.
With enough courage there can be a stepping out of the comfortable paradyme we are presently in; and by doing so there can occur major leaps of understanding and a closer more intimate sense of oneness with all reality. In other words, we can just shrug such a movie off and do nothing, or we can make the effort to actually question and investigate deeper into our own sense of being and existing.
The movie is not important; however, what you do is.
I hope the majority of responses you have received in this thread do not detour you from frequently stepping outside the box.
