Deluxe, Special, Ultimate
The most annoying things about DVDs are the different iterations that they produce. This wouldn't be so bad if they released them all at the same time. No, they release the normal version, then a few months later release the Special Edition. Then a few months later release the Deluxe Edition. This is especially true with films like Terminator 2.
If you look at all the different versions, it is incredibly unclear which one is suitable for you. You would think the latest version would have everything, but no.
It's rediculous that the MPAA expects innocent customers to be able to tell the difference between all these different editions. If they really cared about the customer, they would release all the different editions at one time and make it clear what one edition has over the other.
It's just downright stupid.
