DVD's and Deleted Scenes

Recently, I have seen a lot of DVD's with Deleted Scenes in the special features section. And I have this thought that they aren't for the public's benefit, but instead to make the director look smart. Most of them are horrible and I wish I hadn't seen them in the first place. It seems obvious that they should be cut, but I imagine that the director cuts these stupid scenes and then when the DVD comes out, the big companies decide to add these as a bonus. This in turn makes it seems like deleting the scenes was a much needed thing and in turn - directors are geniuses...
