I have to say from an early age I learned to hate pan and scan in pretty much every case once I figured out why I was having trouble seeing what people were pointing at in movie, or why important text was incomplete onscreen.

That being said I wish modern movies that try to recreate the look of movies from the 40s or the 50s would use fullscreen since when they get everything else right it is just distracting to see them in widescreen. When everything else looks like it from a period film why not complete the look with the aspect ratio?
