The Essential Smallville

The Essential SMALLVILLE

By Douglas Meacham (with contributions from Trentus Magnus)


Welcome to the Essential SMALLVILLE! This list is a compilation of what I believe are the must-see episodes of a show that is near and dear to my heart. It has been a large part of my young adult life. This list dates back, in rudimentary form, to as far as 2007, before the series ended. I rewatched the show last year to create this finalized list for posting on the Superman Homepage in time for the 15th anniversary of the show’s airing. It reduces the show to a little more than half the total episodes, and it’s my hope that it will serve as a good guided tour of the series for new watchers and a refresher for seasoned ones. As mentioned above, Trentus Magnus was very helpful in contributing his feedback and opinion on which episodes should be included. He covers the show in depth during every eight episode of his podcast “Trentus Magnus Punches Reality”. I highly recommend giving these episodes and the show in general a listen. I also invite feedback from you as well. You can e-mail me your opinions and viewing experiences at In the meantime, up, up, and away!
