We should also keep in mind that classic Spock is older, so if the new, younger Spock is less willing to bend the rules, that may be due to immaturity. Like, say, using too much T, and not enough N. That can change with age.
I forget what the life cycle is of a Vulcan. They could both be relatively young. If there is also an important difference in the personalities of the other characters in the newer version, then damn, may have to separate the two.
I am recalling scenes like the one shown below, at the end of which Spock goes to engineering and provides Scotty with some solution out of left field to solve the current propulsion crisis.
Hope is the denial of reality. It is the carrot dangled before the draft horse to keep him plodding along in a vain attempt to reach it. We should remove the carrot and walk forward with our eyes open. -- Raistlin Majere
