Why so many movies not in full 16:9 aspect ratio..specially Blu-ray?
Howzit guys. Is there a reason for this? We have such fancy TV's now with 16:9 aspect ratios...but when we watch Bluray....
we only have the middle part of our screens used and the rest are damn black bars! :-(

Why dont they just film the movies at a aspect ratio that will make full use of Bluray and our HD TV's? 

Do you guys not get irritated by this?
