Smallville is one of those shows that was never GREAT but it had decent potential.  It was a guilty pleasure that has great moments but was never a fantastic spectical.

QUALITY:
Good.  The picture quality is a little too good, in fact.  So clear that the mundane special effects look even worse.  The sound is crisp and 100% lossless, a must in an action series like this.

BONUS FEATURES:
Making-Of, Deleted Scenes, Featurettes, Commentaries.

The bonus features are ok.  The deleted scenes claim to be in high definition but they clearly are not, a pretty big oversight on a blu-ray set.  This season is easily one of it's worst yet with the absense of, arguably, one of Smallville's most intriguing characters, Michael Rosenbaum's Lex Luthor and one of it's most charming, Kristin Kreuk's Lana Lang.  All that is left is the fairly annoying Allison Mack, Erica Durance, Aaron Ashmore and the overly acting Cassidy Freeman to support Tom Welling's would-be Superman.  The addition of Justin Hartley as a regular character should have been more of an added bonus but it tends to fall flat in the story.  Here's hoping that Smallville will do what is right and finally bring Clark Kent to Metropolis for good and end this once flourishing show on a high note.
