It's a matter of personal taste. I also think the sound volume in theatres now is unnecessarily loud...way too loud, in fact...but if the movie itself is one I really like then I can put up with it, although I'd prefer it down a notch or two.

Another thing I don't like about a lot of movies now is the constant rapid cuts from one angle to another to another in action scenes....such that you can't really see what's going on in a fight scene, because you're only seeing split second fragments of it, rather than seeing some visual flow of continuity such as you would have seen in movies a few decades ago.

Again, a matter of personal taste.

I would prefer not to be subjected to at least 20 minutes of earsplitting trailers for future movies and assorted advertising before I finally get to see the movie I just paid good money to see. One way to deal with that is to deliberately enter the theater about 19 minutes after the official start time. This will get you in just before the feature film starts...and that is what I paid for. I did not pay for the 20 minutes of commercials that precede it.

Again, a matter of personal taste.

(I don't particularly mind if my taste differs from yours or if yours differs from the next guy. Like me, I expect you know what you like, and that's just fine.)

In the really old days you got to see a cartoon before the feature. That was fun. (but it didn't sell anything...) GOSH! I wonder why they now have 20 minutes of ads first...and I wonder when it will expand to 30 minutes of ads first, and a pause for more ads halfway through the feature, and more ads blaring in your face as you finally exit the theatre? Greed never stops, it just keeps encroaching on the available space like developers building on available green space, and that's what you see happening everywhere in this society, because there's only one sacred thing left here. Money. Money is God here in modern North America.
