Could not agree with you more. I saw it without any anticipation and all I could say was "WOW". After the Hobbit is done, I look forward to a day long trip to middle earth. From the Hobbit to the Return of the King, I can't wait.
Also, I read your post regarding the Power Gain material & angles. My projector, Benq W5000, is shelf mounted about 6' off the floor. It projects at about 2/3 of the screen height. Based on your drawing, can I assume I would be ok?
