OK, lets admit, it got some interesting things in it, but most of it are out-takes in combination with the actors explaining who they play, and how great al the others involved are. That's not what I call "Making Of". A "Making Of" should have decent background on how the story came together, how they solved difficult technical problems, how they did the special effects...
As a TV-show for before the movie is in Theaters it may be OK, but as a "Making Of" feature on a DVD (as what I watched it) it stinks, because most of the things explained you already know when you've seen the movie. I don't need a featurette on a DVD with Nicole explaining she plays Satine, that's DULL.
