Anyone fancy troll legs?

For all the Harry Potter fans (well... I am a big fan, so it's probably mainly for me :) ) - this is an original troll legs costume from Harry Potter movie The Sorcerer's Stone (2001). It is on display at the Warner Bros Studios, Hollywood.
A stuntman wore this costume in the Hogwart's dungeon and stomped after Hermione as she hid in girls' bathroom.
It's a very unique costume I would say. I think the nails look especially off-putting, but obviously a troll is not a pretty creature so are troll's legs.
Because Harry Potter books are written with such imagination and creativity, bringing it on to the screen through costumes must have been a massive challenge. I wasn't disappointed and the Wizzarding World created in the movies was almost how I have imagined it, when I listened to the books. 
I am curious if you ever read Harry Potter books dear Atria and if so, did you like them? What do you think about the troll legs costume? I guess it is more boys thing and probably doesn't appear to girls at all :-)
