Re: 30 mins of ads
Nah. The ads are probably the theater trying to take some money because the studios take all of it. The cut that a theater gets for a prime first run movie in the early weeks of release is peanuts. They have always had to survive on stuff other than the movie or the experience inside the theater.
Take away all of the extra annoying crap and all of those places would go out of business.
The studios are only indirectly responsible here. They squeeze the theaters and push them out on the thin ice.
