Well, when I learned John McTiernan wouldn't be directing my hopes dramatically fell. It's his franchise (he did 1 and 3, the only ones which are worth remembering) and I don't think a good Die Hard film can be made without him. It's the same as James Cameron not directing Terminator 3, the result will be turd. Plus for some reason out of all available directors they got the dude who did Underworld... and that's it. Paul W S Anderson probably has a better reputation.
