And it's okay.
To let you know where I'm coming from, I loved the original "Die Hard", it's a classic not just of the action genre but of movies in general--at least as much as an 80's action movie can be. There are really two things that made the original work--the claustrophobia and Bruce Willis. Specifically, Bruce Willis doing all his own stunts. Then the sequels have gotten increasingly ludicrous and have thrown out the excellent claustrophobia element altogether. First he was in an airport, then all over New York, and now all over the eastern seaboard. I predict the next movie will be "Die Hard in Space". But, all in all Bruce Willis still does a fine job (although the stunts have gotten way too ridiculous too) and a cool, familiar character in an otherwise pretty standard action flick works. I wouldn't say this is a great successor to "Die Hard" but it's a fine follow-up to "Die Hard 2" and "Die Hard With a Vengeance".
