Jared Padalecki and Jensen Ackles Reflect on a Remarkable 15 Seasons of "Supernatural"

After 15 seasons, over 300 episodes, and countless demons fought, Supernatural, television's longest-running genre series, comes to an end this week when The CW airs its final episode. What started out as the little show that could on The WB network way back in September of 2005 turned into a phenomenon as one of the first horror series to become a mainstream sensation. As the adventures of the Winchester brothers continued, stars Jared Padalecki (Sam) and Jensen Ackles (Dean) developed and maintained a feverish following that continues to this day. Padalecki (pictured above right), in fact, is already at work on a new series for The CW, a reboot of the Chuck Norris classic Walker Texas Ranger.
