This chick is complaining about a movie starting 4 minutes late? What if her watch was fast?
In Australia the ads usually start a few minutes after the movie is supposed to - we get about 3 TV-style ads (but extended, 60 or 90 sec instead of 30), then a few previews... finally the movie starts.
What pisses me off is that rental DVDs are starting to include previews, and they are part of the intro rather than being a menu item. I've had a few where skipping them is blocked.
