I saw a lion in Africa once, only he was in an animal orphanage. Kinda like that. Sharky's beastly-potential is all stifled, unrealized and he knows it, and he feels belittled. Po'widdle suck.
Re: "pretentious student film" - When I saw the "Happy Birthday Sharky" video, my first thought was something about how this is better than just about any video art installation I've ever seen at any gallery or museum. Unfortunately, follow-up Sharky videos have not had quite the same impact.
