I've been waiting for THIS episode for a long time. They have teased Grodd a few times throughout the season. It was never anything like an extended scene or anything. They gave us just enough to whet your appetite. Well, this episode finally delivered on the promise and it was great. I'm not too familiar with Grodd from the comic books, but I imagine that this Gorilla, when he talks, he actually talks like a human would. But this is TV, so I'm guessing that they had it so that character can talk via telepathy, which cuts out the need for facial animation and bypasses the amount of money needed to pull off something like what you see in Plant of the Apes (the movie, not the TV show). So, they don't have to worry about cheap looking lip sync issues. As for the rest of Grodd, he was f*cking awesome. He looked amazing in everything that he was in. I dug the final shot of him climbing the building and then jumping off toward the camera lens. The negative of the episode was the whole Iris/Barry subplot. I haven't had any issues with their love triangle and their relationship as some other fans of the show do. But this one was a bit heavy-handed that left me groaning.
