Wouldn't it be great to be able to watch a movie without the standard distractions? You know - kids fidgeting, cellphones ringing, the guy who's already seen the movie and wants to tell you what you should watch for.
A well-designed home theater will give you a movie experience that rivals (and often improves on) that of the movieplex, in the comfort of your own home. And you'll have the advantage of being able to pause the movie, make your own popcorn, and enjoy it on your terms!
