I didn't like the camp scene. I found it rather reaching. Why would Spock bother Kirk while trying to climb amount and even point out how much concentration it takes to scale a shear cliff...then cause him to fall. It was forced.
And while the camp fire scene was slightly amusing, I didn't find it memorable enough to look at fondly because like it and the rest of the better dialogue it was surrounded by a bunch of....crap.
I've never wanted to pick an M&M out of piece of crap just because the M&M is savory. NO, it's all gets flushed...
