There's so many great sci fi and fantasy towns like Smallville, Hill Valley, Sunnydale, Silent Hill, etc. My favorites are Hill Valley, because Marty McFly. Doctor Brown, and the DeLorean are from there, plus we get to see it at various points in time. Seoond favorite is Silent Hill from the video game series of the same name. Much more than a creepy monster town. You confront your troubled past here.
