Special Effects Failure: Much of their post-2005 work is riddled with this and Conspicuous CG, The Golden Compass and The Mummy: Tomb of the Dragon Emperor especially. Possibly invoked with the dinosaurs in the Land of the Lost film.
Visual Effects of Awesome: Face it, Aslan was pretty. Much of their pre-2005 work also qualifies (even if the movie that featured it, like Speed 2 or Batman & Robin, was total crap otherwise).
