Check out The Minus Man . A slow-paced movie about a drifter who poisons folks. I don't know why, but the movie works. One thing that's said in the review I've linked to is that the director doesn't give you enough insight into the Minus Man's reasons for killing. It's just the way he is.
Some people dress up with cheeseheads and go to the coliseum. . .
I don't know how accurate the review's comments on the DVD quality are. Zero Effect is Fred's fav private eye tale from the 90's. Here's the IMDB URL since I couldn't find anything else quickly. It's the sort of movie where the lead character narrates a descent into a strange and wonderful alternate universe while you, the viewer, are passively pulled into the madness. In Fred's opinion, WAX largely succeeds where the vast majority of movies in the genre fail.
