1) It’s interesting to see how commercials before a movie translate over onto the big screen.
2) It’s only two minutes of your time.
If that two minutes will help the movie industry to make some more money, go ahead. You already set aside a block of time to see a movie. What’s an extra two minutes? Now if it starts extending into twenty-minute blocks of commercials, that could be a problem.
3) The commercials aren’t interrupting the movie.
They are just something on before the movie. Part of the reason for going to the theatre is to see stuff really big on a really big screen.
4) It’s always funny to watch commercials in public.
In 5th grade the teacher showed us an educational tv show, but he didn’t edit out the commercials. It was quite funny to be in that social situation in school watching commercials. Maybe that’s just the novelty of it (which might be related to point A above).
5) It’s funny to hear people laugh at a commercial they see for the first time when everyone else in the theatre has seen the commercial 50 trillion times.
(This fifth reason was added later as it was a comment made by unlikelymoose below)
Yes, there are some bad aspects to the commercials like putting your mind in the wrong frame of mind before a movie. But watching commercials is like many things in life. You can sit around and complain about it, or you can try to see the positive aspects of it.
