This is a strange movie. The breaks in continuity, leaps of logic, robotic lines and random editing make it a surreal experience. Half a century later, bizarro director David Lynch would make a moderately successful career of it. Other aspiring filmmakers--like my 9- year-old nephew--would not be as lucky.
I genuinely found it engaging. All sarcasm aside, I had fun trying to piece together what was happening while at the same time counting the continuity missteps. It was a bit like that game in the Sunday funnies where you're supposed to find 10 things that are wrong with the picture. There's a shirt on a hanger... Now it's gone... Now there's a glass of milk... Now it has mutated into two empty glasses... At a certain point I became convinced that these "goofs" were deliberate, which is how Lynch fans defend such things. Maybe so. I also got a sense of a very "Airplane"-ish style of deadpan humour, as in the hilariously bizarre scene where a policeman is having a jolly time playing the piano whilst behind his back an escaped convict is pistolwhipping random strangers and forcing a few dozen people into a broom closet. The climactic scene (the titular "murder") is so fantastically contrived (and no less fantastically explained in one sentence) that you're left feeling like you just inhaled a mentholyptus cough drop ...up your nose and directly into your brain. What a trip!!
This film defies all ratings. You'll have to make up your own mind if it's a Lynchian masterpiece or a colossal turd (or both?). But I will say that the music is a real treat.
