I found [this post](http://iconsoffright.com/news/2009/03/let_the_wrong_subtitles_in_to.html) about the uproar over the DVD/BR subtitles for Let The Right One In very interesting. Seemingly arbitrary changes really can impact the scene, and you wouldn’t know the difference unless you’d seen (that is, read) the theatrical version.
Warning: Some spoilers if you haven’t seen the movie. (Which you should. It’s terrific.)
