49. The Mountain Troll
Movie: Harry Potter and the Philosopher's Stone (2001)
At their best, the Harry Potter films represent modern-day CGI and visual effects in their strongest, most eye-pleasing forms. In some cases, though, Harry (Daniel Radcliffe), Hermione (Emma Watson), and Ron (Rupert Grint) grapple with questionable foes, namely the ticked-off mountain troll that terrorizes the young wizards in Harry Potter and the Philosopher's Stone. As the kids jump onto the beast and try to subdue it, Harry and his pals briefly turn into pixelated avatars clinging to a Playstation 2 villain.
