Wow. I noticed over at Jimmy Akin's blog that quite a few people weighed in on Pirates of the Caribbean, but in the comments ran a subtle thread about all time best movie.
Of course, many a Catholic named Gibson's The Passion as their favorite. But I still maintain that for me, the best movie (and the best book) remains the story found in To Kill a Mockingbird. For myself and other attorneys of a certain age, we would like to attain the paradigm of legal ethics embodied in Atticus Finch. A simple countryman who was afraid to take an unpopular position (he knew the reaction it might garner and as a widower with two small children, his first concernwas their safety) but did so because it was the right thing to do.
(Now, this is a deviation for me since most of the time I enjoy what can only be described as "strange" movies or completely sophomoric ones. For example, I know most of the dialogue to Caddyshack, I think Eraserhead is pretty darn cool, loved Napoleon Dyanmite, and was bitterly disappointed in Michael Douglas' lame attempt to remake The In-laws since only the version with Alan Arkin and Peter Falk is worth watching. Oh, and who doesn't love Harold and Maude? Or March of the Wooden Soldiers with Laurel and Hardy? And was I the only person to understand that Natural Born Killers was a comedy, albeit a very, very black one?)
