No matter what goodies or special features are included in the DVD gift set/collector's edition/special edition/early edition/inside edition/etc., it's the movie that matters. If it's good, it's good. Bad, it's bad.
The Harry Potter series
I don't hate Mr. Potpot. And I've watched all the movies. They're good and really well done. I'm just apathetic towards the DVDs.
The Da Vinci Code
Same as with Potpot, but I'm not that thrilled with the movie -- no matter how many doodads are included in the DVD giftset. I'm not even Catholic enough to be affected in that way.
The Matrix trilogy
The first film is good. The last two exist in a different universe. In other words, the first Matrix is out of their league. That's my nice way of saying Reloaded and Revolutions are both ****.
Daredevil
Elektra
Ghost Rider
Titanic
This goes without saying.
