Erase every memory you have of the U.S. version of Skins if that's the only experience you've had with the show. The original UK version is 10 times more insane, 10 times more heartwrenching, and 10 times more stoned. The point is, you'll never be bored. Every two seasons rotates in a new cast of fucked-up teen characters engaging in all-out debauchery, but in a way that's startingly realistic and true to modern issues. Booze, teen pregnancy, depression, and homosexuality, anyone? Not to mention, the series introduces audiences to some young actors poised to take over Hollywood, namely Nicholas Hoult, Dev Patel, and Kaya Scodelario.
