There are some cool shootout sequences, but very few specific sections that make you look back and say, "Man, that part where X happened was awesome!" It's almost as if the game set its bar right from the get-go and never really strays from it, neither lower nor higher. To its credit, BLACK really has zero downtime throughout the course of the game - all of it is awesome, trigger-always-pulled action. But none of it is flat-out phenomenal in the truest sense of the word. There aren't really any moments in the game that rise above everything else around it, creating any sort of contrast within the context of the game.
This is a little hard to explain, so I'll use a movie example. Raiders of the Lost Ark is, in my opinion, the most perfect movie ever made. It's not my overall favorite, but I have absolutely no faults with it and it's fantastic all the way through. But even though I love every second of the movie, certain standout sequences come to mind when I think about it, like the face melting sequence at the end or when Indy simply shoots a man after an impressive display of swordsmanship. Or the part where Indy is being dragged by a truck and fights his way into the cabin. Or hell, the classic intro. I could go on and on, but you get the point. Each of these sequences stands out on its own.
This isn't really the case with BLACK, however. Some sections are cooler than others, sure, but only slightly so. You're always shooting at soldiers and things are always exploding. There aren't sudden shifts in this scenario where you're in total control one second and then being chased by a helicopter the next. The environments change, but the action doesn't.
Really, this is more of a missing aspect of the game than a fault. What's there is great, but had there been something more every now and then, it would have shaken up the feel of the entire game.
