Yippie kay yay! Great addition to the series.

Rating: 7/10 (2 October 2010)

First of all I've watched both the PG-13 and the Unrated versions. I have to say that there's very little difference yet a lot at the same time. Most of the difference is the dialog rather than the violence but this connects better with the previous installments.
This is one crazy action flick. The scale is larger than any of the previous Die Hard films and the action breaks the law of physics in every way. This is not a stealth movie. John McClane is hungry to kill and he announces his plan to the villains throughout the whole movie and still ends up accomplishing his goals in the most satisfying way. If there is one movie where one-liners don't bother me, it's this one.
The writers did insert a few dramatic moments here and there and adds more character to the John McClane we all knew and loved. It's a moment of reminiscing of the previous Die Hard films. The movie is a tribute as well as it's own stand alone film.
As crazy as the action is, the special effects support this. I've seen movies that use the silliest special effects (such as Transformers 2) to support the action. The fourth Die Hard has good special effects. It's not the effects that make the scenes unbelievable, it's the action. Yet it's all very good fun. This is a non-stop ride of explosions and some at-the-edge-of-the-seat stunts.
Justin Long is funny as well as likable. He makes a believable performance and is a great sidekick. He was worthy of Samuel L. Jackson's replacement. His character contributed some comedy and it was interesting to see such a different character interact with John McClane. McClane's daughter, Lucy is back in this sequel and is the perfect action star's daughter. She is spoiled and independent towards her father. Only, I do feel that something is missing in the transition of the change of her character. It feels a little rushed and if it was a little bit more rushed it would have been as if Lucy just wanted help from her father at troubled times.
Overall it's an enjoyable movie that you can watch at a weekend night. It leaves you feeling good, entertained and rested after work. It's over the top action scenes are something you've never seen before and you should definitely check it out.
As a last note, I know that there are some rumors floating around about a fifth Die Hard movie with it's supposed title to be "Die Hard 24/7". I would love to see another Die Hard but let's hope they just call it Die Hard 5, not Die Hard 5.0 but Die Hard 5.
