As the first episode of the offbeat, wacky Disney series Gravity Falls, the pilot "Tourist Trapped" starts the ball rolling and introduces several key points to the series. When siblings Dipper and Mabel Pines are sent to the small town of Gravity Falls, Oregon, they think it will just be another summer, spent for their part-time con man great uncle (or, as they call him, "Grunkle") Stan, who initially seems to simply care about money but eventually reveals a more caring side, at his tourist trap The Mystery Shack. However, not all is what it seems, as Dipper finds a mysterious journal in the woods and the twins realize that this summer could be much more interesting than they originally thought. After reading the journal, Dipper becomes concerned that Mabel's new boyfriend, Norman, is a zombie, and tries to rescue her before it is too late. Altogether, this was a quirky, entertaining and very funny first episode of the series, with an interesting mystery beginning to form. The five major characters who appear in the show the most (Dipper, Mabel, Stan, Soos, and Wendy) are introduced, and the show immediately manages to find the balance of mystery and comedy, becoming an entertaining first outing while beginning the overarching plot of the series. And just when you think it's over, one final twist is added at the very end of the episode before the credits. After several years of relatively disappointing television, Disney finally seems to have hit their stride with a darker, funnier, more intriguing show designed for enjoyment by children, teens, and adults alike. The beginning of a great series.
