I remember after the first Bourne movie (which had a pretty static camera style) they changed directors and the second two movies use this shaky camera effect, which was quite new at that moment, or at least not as overused (I remember noticing it). It worked well then. They also started the trend of the camera pointing at the person after he starts talking, like the cameraman isn't sure who's gonna talk next and just improvises.
But it's true that nowadays it's overused and they shake it way too much, it's like the cameraman has Parkinson's. They must be purposefully shaking it while recording, instead of just holding it on the shoulder and getting a natural shake.
No troll is too much for me to handle. I rehabilitate trolls, I train people. I am the Troll Whisperer.
