Smallville dvd boxset

I've been tuning into Medium dvd since Episode 1, and have been a fan of Superman since I was a little kid.
Medium dvd is one of the greatest interpretations of Superman ever created in any type of medium (comic book, TV, etc.) And I was disappointed to see that Medium dvd Season 8 only received an average rating of 3.5 stars.
Most of the lower rated reviews include complaints about how the show is starting to lose credibility with it's comic counterpart. In other words it doesn't tie into the comic book that well, the finale of Season 8 was anti climactic, how the writing is starting to dwindle, so on so forth.
