If you're a movie buff that relishes watching the latest releases on the big screen, but can no longer cope with the general public ruining your show, you may want to consider creating your own cinematic experience at home. I've lost count of the number of times that a movie I've been watching has been interrupted by teenagers kicking at the back of my chair, or babies screaming, or people's mobile phones going off during a crucial part of the story. It seems that no one in the cinema is even interested in watching the actual movie.
Sound is the other important factor. The more empty the space, the better the sound will be. This means that you do not want to be cluttering your home theater with a lot of furniture. A comfortable seating arrangement is imperative, but you should try and keep it to a minimum to create the best spread of sound in your room. There is a good reason why the professional cinemas are so open, and it's to get the best sound quality possible. Another thing to consider, while on the subject of sound, is interference from outside noises. Having a loud truck drive past your house while you're in the middle of a movie can be very distracting, as can the neighbors shouting at each other. If this is the case, you may need to consider sound proofing your room.
Finally, you want to be able to automate the functionality of your room as much as possible. This includes having remotes at hand and easily accessible, and keeping your movie library neat and catalogued so that movies are easy to find. You can also get motorized blinds, so that you can dim the lights, lower the blinds and start the movie, all at the touch of a button.
