WALK THE LINE, fine performances by Joaquin Phoenix and Reese Witherspoon

I am rather ignorant to the details of Johnny Cash (and June Carter)'s history, and I don't remember ever listening to any of his songs before (well, I might heard some when my dad was playing it, but I don't think dad was that into Johnny Cash either), thus I can only evaluate the biopic based on whether it could hold the attention of any viewer who does not know anything about its subject. After all, I'm not anal when it comes to judging the factual accuracy of biopics (I can never understand why some people like condemning biopics that much just because they aren't accurate enough, yeah, I'm looking at those who complained about 'A Beautiful Mind' not examining John Nash's homosexual tendencies), it's more about whether it 'works' for me as a film.
