OK--if you have read the plot synopsis or some of the other reviews, you have seen that this film alludes to Sartre and "No Exit." The director's name, The Existentialist," certainly is one point of reference. But you need to get through to the end to really appreciate this allusion.
What else can I add? The acting is uniformly bad. Of course, this movie is a movie within a movie, so what else to do expect?
The camera work is typically bad. Think of the worse images from "The Blair Witch Project," and you will see what I mean about the cheap (which is not necessarily the style, unlike "Blair") camera work.
The one aspect that compelled me to give my hour to this film is the potential for a post-modernist critique. This film is self-referral and pastiche, both hallmarks of post-modernism. Stay for the last minute or so (after the end credits) and watch this sequence. This last moment of so explains--to me anyway--why this film was worth my time, particularly the monologue about the "death of the author" and the death of the director. Lots of intellectual fun for me.
Again, if you are interested in post-modernism, cheesy movies, or allusions to Kubrick's "The Shining," take an hour, pour a cup of coffee and waste some time--ironically what many who are reading this do on a regular basis anyway. Or do they? Are they simply playing their roles in the director's script?
