WOTG was a unique movie, if people can look at one big thing:

Did you notice that the Gargantuas displayed a somewhat noticeable array of facial expressions\emotions? I say that because one thing I noticed was that the actors were able to move their eyes in the masks. That natural eye movement greatly accented their emotional and facial displays.

The scene where Sanda picks up the tree trunk to smack Gaira with-look at the crease in the forehead of Sanda, and the anger in his face. It's such a cool thing. Add the moral conflict between the creatures and the question
of one playing "brother's keeper" for the other, and you get a somewhat different type of film.

The Gargantua designs were quite neat too, a different kind of creature.
