Tonight's Terra Nova premiere isn't just a mash-up of Jurassic Park, Lost, Avatar, Land of the Lost, and Steven Spielberg's family unity ideals. (Families are based on determination, right? Right!) It's also another entry in the "Welcome" genre — that is, the films and TV shows where a character says "Welcome to [The Title of This Film or TV Show.]" Is our list exhaustive? Perhaps not. Is it exhausting? Perhaps. Is it fun to think about other lines of dialogue that both Cher and Sean Connery have said? Certainly. Welcome to network television, Terra Nova.
