In my case, I've spent the last 2 years saving, researching and investing quite a lot of money to build my own home theatre. Why? Well...
Because I love cinema, and I can't stand at the theater with people behaving like animals... I'm sorry but I can't
I want to enjoy the experience, I want to forget about the rest of the world for those 2 hours and, as a director/photographer myself, I RESPECT tremendously the effort and work putted into the production of any kind of art.
I hope you like it, it's been quite a long ride but I'm already saving for an upgrade soon, but for the moment I'm pleased as hell, I just moved to my new home with my girlfriend (who I met thanks to a local U2 forum more than 8 years ago) and, well, we are very happy with how everything ended up.
The entrance:
This is where I have those little specifications. From top to bottom, Bravia Theatre, 3D World Created by Sony, BluRay Disc, DTS-HD Master Audio, Dolby Digital 5.1...
Inside:
An overall look of my HT.
My Sony Bravia:
A 3D Bravia, the Sony KDL-42W805a, last's year top of the line, at least where I live:
My BluRay movies:
Some of my collection, including (I have new ones, but I didn't take the picture of those yet):
Triple Feature from Stanley Kubrick: 2001 A Space Odyssey - A Clockwork Orange - The Shining, It might get loud, The Cure Trilogy, Gran Torino Steel Edition, I am legend, The Karate Kid, Blade Runner 5 Disc Collector's Edition, Garbage One Mile High Live, Edward Scissorshands, U2 360, Cloudy with a Chance of Meatballs 2 3D (I still have to buy the first one), The Counselor, Life of Pi 3D, Prometheus 4 Disc Collector's Edition, Twister and Days of Thunder.
My CDs and some DVDs:
A bit of everything, including the whole U2 collection obviously, some japanese music, jazz, blues, classic rock...

Beneath the PS3 and the HT:
Some books, a couple of DVDs and 2 PSMove.
