Why the Foreheads are So Huge in Code LyokoAlternate title: "Why Their Foreheads are So Huge."
Alternate alternate title: "Why Their Foreheads are so [bad word of choice] Huge."
I liked (and still like) the art style of Code Lyoko. It is anime-like*, insofar as having a barely-deviating, angular face formula (Ulrich with his unique facial structure aside) with a small, triangular nose, a wide jaw, and a lack of visible fingernails.
However, Code Lyoko substantially differed from the "anime style" I knew: their eyes were roughly parallelogram-shaped with only black dots on the inside, rather than being huge semi-ovals with colorful irises and shine spots. I felt eyes that were too complex obfuscated the characters' emotions and detracted from the experience by making it too obvious they were artificially ornate, and acted as obstacles to the viewer's emotional resonance with them; the simple yet "realistic" eyes of Code Lyoko's art style allowed them to express themselves (especially in glaring) without looking cartoony.
