Everyone comes at things from their own area of expertise. I've had the honor of seeing Danny effortlessly dump someone on the mat and completely immobilize him with almost no body movement at all, so he's going to pick up on things the rest of us might gloss over and just put down to Hollywood.
I enjoyed the movie, and my only big "Oh what BS!" moment of disbelief was when the jump jet flew under the overpass and between the concrete freeway supports. That just is not going to happen.
Also, I won't give away the ending, but Hollywood completely underestimates the damage a bullet will do to the human body. Does anyone remember that 80's flick with Nick Nolte and Eddie Murphy, I think it was "48 hours"?
In the end Nolte shoots Murphy in the shoulder with a .44 mag so that the bullet will pass through and get the bad guy who's standing behind him holding him hostage. Later Murphy is shown walking around with a bandage on his shoulder. If they had been realistic they might have shown him with a cauterized stump instead.
All in all, pretty good, but I didn't like it as much as the one with Samuel Jackson.
