David Mack does perhaps write the most cinematic of violence in treklit: especially when one hears how much soundtrack influences the composition of his writing, a la the Bombay and James Newton Howard's King Kong score in Harbinger. But he is also rather diverse in how he writes violence: there is no one style.
Yeah ... the hand-to-hand violence in Destiny was actually the one element that really didn't jive for me with what has been established in televised and filmed Trek. For example, the scenes on Dax's ship, where her security officer (Kedair?) is taking out Hirogen boarding parties with neck breaks, and Jasminder on the Enterprise taking out a hirogen with a sword, just didn't match the TNG security officers we've seen - Starfleet isn't made up of ninjas! It kind of pulled me out of the story, because it seemed uncharacteristic ... I really like this story, but do wish some of the more intense violence would be toned down, as it doesn't seem the right fit for Trek, in my opinion...
I have enjoyed many of David Mack's books, but as far as violence goes I am looking for less violence and more exploration/discovery/science etc.
Actually, that sequence was inspired by the John Williams-conducted version of Gustav Holst's "Mars, The Bringer of War" from The Planets. Howard Shore's score for King Kong was my inspiration for the sections of Vanguard: Reap the Whirlwind set on Jinoteur.
