I agree with what everyone else here said. I do hope he keeps a significant amount of that wild attitude, but has it tempered both by maturity and by Spock. I think that would be an excellent way to move into developing the relationship between Spock and Kirk as we see Spock sort of reigning Kirk in a bit more.
Pine did a fantastic job managing to be like Shatner's Kirk but also his own Kirk at the same time. It was a hard job to pull off and he did it.
