Karl Urban does a good DeForrest Kelly, but the character is given very little room to breathe in the new films. If you cut out the metaphors and the one-liners he is reduced to little more than comic relief and a part of the MacGuffin that saves the Captain from death. Quick aside on that, why would they need Khan alive if all that was needed was his blood since they had about 70 other people with the same type of blood sitting right there? Anyway. Bones was the final part of the trifecta of friends who would travel the stars together. He was Jim's confidant, advisor, counsellor and friend. He had a love/hate relationship with Spock but always had a grudging respect for him. The new McCoy is more of a caricature of the original providing neither influence nor a sense of deep friendship with either of the other two protagonists. There is just about enough there to give the impression that the character is the same person we know but it is nothing more than a decent impression of a once great character. Kudos has to be given to Urban who seems to revel in the performance but it is disappointing to see the doctor reduced to not much more than a cameo.
I.T. Consultant, technophile and Doctor Who fan. I like to talk about tech, take films apart and make excuses for Doctor Who's continuity errors. No other show has the power to make me feel like a big kid.
