I don't like this. McClane again looks like the ubercool superhero again, just like in Die Hard 4. He isn't supposed to be that.
Yeh, I too hate it when a character experiences growth over the course of a series. Oh wait. No I don't.
By the time DH4 rolled around, John McClain had already dealt with three major terrorist situations. He simply was no longer the poor unsuspecting and out of his element everyman, and it's a damn good thing they didn't try to play him that way, yet again, because that would have been even sillier than taking out a helicopter with a police car, or riding on the back of a jump-jet. The experience of the first three films made him into a certifiable badass, and I'm glad that's how they're playing it.
