If you’re a fan of MTV’s Teen Wolf, you might have noticed something subtly off about werewolf appearance this summer season.

Is it Kali’s insane toenails? No, those are mean-looking villain feet. Is it Deucalion’s demonic transformation? Nope, once was enough, thanks! I’ll give you a hint: every werewolf who’s taken an innocent life has to see these baby blues in a mirror. And this summer, it’s different.

Creature design has changed subtlety but considerably over the course of Teen Wolf’s triumphant three seasons. Some of those brought improvement: Peter Hale’s embarrassing alpha-beast CGI in season one was succeeded by an excellent combination of make-up effects and graphics for the Kanima. The facial prosthetic for werewolves changed, and in season three the characters abstained from the facial shift almost entirely as an indication of their respective control over their abilities. When they do flash the fang, characters like now have a whole mouthful of predatory chompers instead of two measly incisors; if some crazy buff guy turned around and ran at me with those teeth I’d shriek and probably get religion.

All is not classy horror homages in Beacon Hills, however. In one crucial area, the artistic design staff for Teen Wolf have made a baffling choice that’s been bugged me all season: neon day-glow eyes. The red and gold eyes of werewolves remain more or less the same, but for some reason they chose a different hue of beta-wolf blue for Peter and Derek. This is particularly noticeable in episode 3×08, “Visionary”, where we learn the meaning of blue vs. gold. In season 1 and 2, beta werewolves who had killed an innocent had icy, cyan-blue eye color that basically looked like they’d been standing too long next to the Tesseract from the Avengers film. It was looked cool. Better, it looked powerful.

Then in season 3, the CGI effects change, and we get the Fern Gully upgrade:

Why, show, WHY must you ruin Ian Bohen’s on-screen gravitas with giving him eyeballs the color of a Dancing With the Stars costume? Does it have to be vivid neon? The icy white-blue hue was cool because it actually resembled how a normal eye color might look if backlit with magic. People with blue eyes tend to be in that lighter color range (just google Chris Pine), not the electric blue of an anime character.

Every time I saw the fake-y-fake blue eyes this season, it pulled me out of the dramatic moment. The change may seem inconsequential, but details are everything when you build a fantasy world and invite viewers to see it as plausible. Since most of the dramatic events centered around Derek Hale this season, you couldn’t get away from it. Here’s a side by side comparison of Derek in season one and Derek in season 3…

How anyone would pick the second eye tone over the first baffles me. His eyes in the left image are eerie; his eyes on the right look like cheap, light-reflecting contacts a teenager might by for a rave outfit.

Visual consistency is a pet peeve of this fan, and television can be held to the same standard as any other artistic effort. When the central image of a shot focuses heavily on a single detail, as Teen Wolf so often relies on the super-powered eyes of its monsters, a small change can have a huge consequence. Production decides whether the audience will see a hero that looks bad ass and mystical, or whether they’ll see an actor with overwrought special effects.
