Eighty years ago there was a famous theatre critic named Alexander Wolcott. One evening he was watching a play (don't remember the title) with a famous old-time actress, Tallulah Bankhead. He asked her what she thought of the play, and she said "There's less to this than meets the eye."
And, for me, that really sums this movie/play up. If it's meaning(s) don't, pardon the expression, "resonate" with you, don't worry about it. They don't "resonate" with me either. Though, I'd have LOVED it if Jim Morrison had knocked me up before he croaked. But that's for another chapter of bad drama... ;9)B
