Re: Die Hard 4 in the works.
Hammer, good points. I can see what you are saying about character development for McLane but if he develops into just another supercop, why go see the movies? This is why 16 Blocks resonates as a better old-man Mclane movie, to me. I am all for some development in character over a series of movies...to a degree (Did Indiana Jones change much? Did Capt. Kirk?) but to change what made his character
unique among action heroes is kind of a let down. Sure, he can be more sure of himself as an older, wiser McLane. But then, do I really need or want to see that?
The bigger point to me would be, if you replaced the character John McLane, could the movie still work? If you say yes, then it really isn't a DIE HARD movie...it is just another action movie. Granted, going on a very thin trailer makes it hard to be sure but if this is any indication of overall movie, it clearly looks like any generic rent-a-cop would do nicely.
As you mentioned, Bourne was a genre busting movie. His character is very integral to the movie and how he approaches things is very important. Methodical, well thought out, serious, subtle, etc. If in the third movie he became a wise-cracking, two-gun shootin' hombre from a John Woo movie, would it still be a Bourne movie? I don't think so.
Speaking of Woo, I would add either THE KILLER or HARD BOILED as another genre busting movie for your list. The style of those movies (back to the lesser known A BETTER TOMORROW) is still reflected in today's action films, though I think the Bourne movie seriousness has taken over. That said, I look forward to HOT FUZZ to change all that with its glorious return to the Woo standard!

I know this is a lot of handwringing but it is mostly for fun conversation. I really am not that invested as the DIE HARD franchise quality dropped a bit with 2 and became a non-player with the 3rd. 4 at most will be a curiousity that I hope is better than it looks.
Enjoy!
