The movies should be an escape from every day life. The theatrical experience should be a sort of sacrament, otherwise there's far less incentive to leave the house and pay 10 times as much to watch a film a few months earlier. Luckily there are still a lot of theaters in my town that are not so aggressively trying to capitalize on their captive audiences. Mark Cuban gets this, but I'm sure whoever he sells Landmark to won't. I'm done with going to see movies at the megaplexes though.
I pay a good deal of money to see a film in which I am so bombarded with ads beforehand that its ruined the film experience. The last film I saw had a full 15 minutes of ads and trailers before it started! My girlfriend asked me if we could just leave and get our money back.
I feel like it's never actually been that good, but I think it has actually gotten worse than it used to be. Possibly doesn't help that I remember actually being interested in movie trailers, whereas mostly now I'm just bored by them. That ties in a bit with Ebert's point the first, but to me it feels like it goes further; most of them look rubbish and any exceptions I've normally already heard about via an internet.
The problem across the board really seems to boil down to "megaplex chains are bad for movies." There are a lot of specific line items but they all end up sharing the common denominator of "this wasn't a problem until the rise of big box multiplex theaters."
I've told my parents that I like movies but I hate going to movie theaters before and I think this might be why.
If we were more than 10 minutes late, we'd just go to the mall or arcade or something instead.
They even provide an RSS feed of new trailers.
(Yes, I'm being somewhat snarky, but I'm also genuinely interested in your take on Flash-based sites. Is it an issue of "Flash is already installed and QuickTime is not" or something beyond that?)
At some point, research was commissioned by movie industry types to find the viewers' "time of highest alertness", i.e. when to deliver the best scene. It turns out that viewers are most focused in the first 20 minutes, which is consistent with most research efforts in other fields (see the usual stuff about 15 mins presentations etc).
Trailers were already being shown in that timeframe, to allow for latecomers, so adding regular ads was a no-brainer.
Simple way out is to walk in to the cinema hall about 15 mins after the scheduled start of the movie - works for me every time.
