"Too many characters?!" "Boring?" Well, I won't try to change your opinion but I WILL stick to my own opinions that you're wrong about the first (most movies have as many or many more characters than featured in MURDER, MY SWEET) and that your attention span today might be more seasoned in another five or ten years from now, after which, perhaps you'll get more out of this movie with a second viewing.
Don't take it as an insult with my "short attention span" theory. It's true of everybody at one time or another. I've seen quite a few flicks I either didn't like much or thought were okay but mediocre; but increased age has heightened my appreciation and perceptions of those same films that hadn't impressed me when I was younger.
Okay folks, show's over, nothing to see here!
