We need a new kind of man-eating plant. That's pretty much what I took away from this trailer, in which the Joker, Killer Croc, Bane, and Poison Ivy strut their stuff. Ivy has a bit more stuff to strut than the other three, but her choice of boss monster leaves much to be desired. How about a man-eating plant that merely tears the body into bits, which then fall into the soil below to help nourish its roots? Do they all have to be bulbous Audrey rip-offs with teeth?
