I like extras. A good film just doesn't feel complete on dvd without a couple of extra little things to entertain you next time you have half an hour to spare. As a student I can't afford to have several dvds on order at a time, so i like to get the most out of every film i do get. Commentaries, featurettes, original trailers, interviews behind the scenes gossip, deleted scenes, alternate endings... love em.
Of course there are plenty of extras which are plainly just a waste of time.
Cast and crew bio's and filmography are pointless- IMDB handles that very nicely thank you very much- besides, information is out of date on the dvd within a month of purchase.
Web content/links/pretty much any PC content- ****e. Always utterly unusable. I don't know who they get to design these bits but i can't stand them. Why do i get prompted to install interactual player every time i watch that dvd on my computer? Damned thing...
Stills galleries/text content- can't see who on earth would want to look through them on their telly, the 50hz flicker gives you a headache after 10 minutes. Put it on a website for the people that want it!
A couple of dvds that wouldn't be the same for me without their extras;
This Is Spinal Tap- Marvellous. So much extra material, and brilliant in character commentary track.
Predator Special Edition- Great stories from behind the scenes. Good to watch with the lads after the pub.
Conan Special Edition- Absolutely hilarious audio commentary. Arn is ****ed as a newt, John Milius stoned. Count how many times arnie says "Exactly". And count how many times john says "look at her she is so beautiful...."
