Query: Great Movie Lousy DVD

I would of given this DVD 5 stars if not for the previews. Right before the menu comes on there are five previews which spoiled the whole disc. You cannot fastforward through them either so you are forced to watch them everytime you put the DVD in the player. Let's hope more studios do not pick up this pratice like they did with VHS.
