I bought this DVD a few years ago, and I watch it every Christmas. The Bob Saget episodes are the best (and the set is still the best set the ever designed), plus the theme song on those episodes sounds a lot better and funnier with words. The Tom Bergeron episode is okay, but I never found him as funny as Saget and I even stopped watching the show on a steady basis. Plus the Bergeron episode on this disc reuses clips from the Saget shows (such as the lights falling off the house after the guy takes the ladder away) and Bergeron just does a joke for these clips that does not add to their funniness.
The Saget episodes (which are the 96 and 97 Christmas specials) I would each give a 5/5 too. The Bergeron episode (the 2002 Christmas episode) I would give a 2.5/5 rating.
