I've enjoyed the first Die Hard very much, that's a classic, and kinda liked the second one... I've seen only about 10 minutes of the third one on TV, and it didn't seem so good. It appears that reviving old franchises and movie series is the new movement for Hollywood (Rocky Balboa, possibly Indy 4). All I wanted is BTTF4 with a decent farewell to the screens by Michael J Fox and Christopher Lloyd.
