Yeah, 16 Blocks was disappointing, but come on ... this is John "Yippie-kye-aye, Motherfucker!" McClane.
Also, bassguy, the title was changed because "Live Free or Die Hard" is based on the motto of a US state, "Live Free or Die". It was changed for the international release because audiences might not get the title otherwise. But since this is probably going to be the last Die hard film (at least with Bruce Willis), I figure they should have followed the trend of the previous films - Die Hard, Die Harder, Die Hard With A Vengeance - and named it Die Hardest.
