...And you say you haven't watched much SeaQuest DSV?
Your description fits that shows boy-wonder much, much better than it fits ST:TNG's Wesley Crusher. (IMHO)
Interesting. I always regarded the ST:TNG characters as much more three-dimensional than the ST:TOS characters. But I can't remember young Wesley having as much depth. I dunno. I may just have forgotten most of the ST:TNG episodes while I've seen most of the SeaQuest episodes in syndication on the Sci-Fi channel. It will be good to watch TNG again this fall on TNN.
