Pretty much sums up my opinion exactly... I love any interviews, documentaries, etc... but I could care less about photo slideshows and whatnot... super 8 versions of the film- wtf is that? why would I ever want to sit down and watch a shitty version of the film when I can just watch the DVD? I guess in some sense its cool to have it, in an archival sort of way, but i couldn't imagine it ever being watched..
I like the special features on the Robert Rodiguez discs a lot, the short film school things where he shows some of the methods he used to make his films
I recently just gave this interview a watch and I found his commentary to be very interesting, particularly his words on his character in the film
