Help me with something...

So I went to see a movie today.  What is it with the people and their need to react audibly to movies?  I don't get it.  With the exception of laughter at appropriate times, there really are few other noises a human needs to make during a movie.  Some guys I think just can't help themselves.  I saw this movie in Nashville and I can debunk the stereotype that certain ethnic groups talk to the screen during movies because it was a mostly caucasian affair today.  But that's besides the point.  I'm just trying to understand the mentality of these dudes who think they need to vocalize their reactions in such a loud manner.  I'm not talking about the involuntary shrieks or gasps that a surprising moment might bring.  I'm talking about the guy who cheers when the hero triumphs over something.  Or when anything a person allows out of his mouth actually forms a sentence much less a short phrase.  SHUT UP!  Is what I say.  Well, I don't "say" it per se, I actually think it.  I'd hate to be hypocritical... or perhaps... the target of a violent attack should I offend some monolith with my superior thinking.  The big one though, what's with the clapping at the end of the movie.  Who are you clapping for?  Do you think that the producers are in the building?  Is the director getting updates from the theater?  "Did they clap?  No?  Crap!  We must have done something wrong..  I knew that cameraman was an idiot!  Thanks for your help Bob."  And while we're on the subject of movies, I'm tired of the little make-you-sit-though-the-credits-to-see-the-last-scene scheme.  Dude, just make the end of the movie the end of the actual movie.  I don't need to know who the Best Boy or Key Grip guy was.  Give me a break, that is really only for the dudes that are there to see the movie with his friends.  "I told you I worked on that movie cracker!  Give me my five bucks!"  Why do I have to sit through that crap to see the final scene?  Problem is, I'm starting to do it at all movies now so I don't have somebody say, DID YOU SEE THE LAST SCENE???  And I didn't and now I feel like an idiot.  But then when there isn't anything at the end of the movie, I just wasted 20 more minutes that I could've used elsewhere.  But hey I found out what washed up one hit wonder rock star wrote that song from the scene when that band was playing in the bar.  Useless, much like the crap that some dude is spouting off with during a movie making me miss out on dialog I wanted to hear...
