I think a possible ending could have been after Seymour is eaten the guy who is on the flower diet eats Audrey (the plant)or tries to and gets eaten. I was trying to figure out if that character was put in to make you think he would eventually eat Audrey, or comic relief, or the opposite of Audrey in regards to Audrey is a flower/plant that eats people (unlikely), guy who eats flowers (unlikely). Both are on opposite sides, and they should have had a showdown. I cannot remember in the more modern one with Rick Moranis, was there a flower eating guy in that one?
