David Denby is a pretty smart guy, he writes movie reviews for a living (in part), he's well educated and well read, and he thought the same thing as you. The reason that I thought this was about suicide was: The bus stop had been discontinued, and the only person who waited there throughout the film was someone who was presented to the audience as someone who was out of touch with reality and rather hopeless. I guess also the fact that I didn't really see beyond the horizon for Enid and had a hard time figuring out even where she would go once her options had been cut off...

But you know, art is certainly subject to interpretation...
