Home video has been both the best and worst thing to ever happen to the cinema.
Video allows us to see far more movies than we would otherwise be afforded.  We can stop and start the film at our own leisure and examine it at our pleasure.  We don't have to venture out of our safe little cocoons and deal with miscreants and malcontents, yes, I'm talking about you Ducky.
But, because we do see so many movies, it becomes harder for originality to shine, and the movie companies tend to produce, ahem, less than original films aimed at the lowest common denominator because those films will traditionally turn a profit. 
By being able to pause, fast forward or rewind a film, we lose some of the intended artistic vision of the director.  We also lose, by examining videos, some of the mystery formerly associated with the cinema.
By watching films in our living rooms, we do avoid people like Ducky, but we also learn bad habits and miss the communal sense of a film.
But, since video also lets me watch "Animal House" whenever I wish, I shall forgive the rest.
