Live Free or Die Hard(Die Hard 4)- Opinions?

Hi guys.Love the Die Hard Trilogy. IMO they are the epitome of action movies. Can watch them over and over. Nothing like some good R rated action and violence. Just picked up Live Free or Die Hard(2007). Planning on watching it tonight. I have had some mixed views on it. Some don't like that its PG:13 and that John McClane doesn't say his trademark yipeekiyee ************.What are your thoughts on it?
