It's been a long, long wait for Lost fans. After a kickass season finale, we were left with months and months of waiting to see what happens to our island castaways... The above video clip is the extended trailer for Season 4 that recently hit the web. Hell yes. That ought to get you at least a little excited for the new season. You get a glimpse of all your favorite characters, as well as some new ones... including Ken Leung with a gun. Can't wait for things to get started again. The new season premieres January 31st, on its new night and time, Thursdays at 9pm.
