The old Lego Trolls are interesting. Only their arms/hands move which limits their usability. Lego should articulate the legs, at the very least. Look at the Minifigure compared to these Bigfigures. Even with their limited use, people still find new things to do with them. Check out this Lego Troll by nita_great. It looks ready for a night out with friends. They even posted a photo showing the parts. So you too can dress up your Trolls, or even your Hulks.
