Was he able to feed Michael or did he have an IV drip in his riverside shanty (that by the way, is somehow at the bottom of a well/sinkhole/black hole)? Or, if Michael is supernatural and doesn't need to eat, didn't that fact concern the bum/fisherman?
I've seen this movie four times, but the complete lack of logic, plot, and characters (only a slasher movie could lack all three and still be considered a narrative film) mean that I forget everything except vague details 10 minutes after I see it. I only remember strange details, like being woken from a fever dream. "I know there were kittens in a barn...and a little girl crawling through air ducts...I have to stop taking Vicodin before going to bed..."
