I've long had a theory about Wesley and TNG. That it was really supposed to be 'his' journey. The series begins with him being something of an audience identification figure, with plots revolving around his rise through the ranks, his first ever 'official' away mission, etc. And one of the last episodes in the very last season is all about him leaving Starfleet, giving a nicely circular sense to his story.
I mean, TNG was always an 'ensemble' drama. But like him or not, Wesley clearly was always supposed to be a 'focus' character, and he is exactly that. A focus. Particularly in the early seasons.
(Does it sound
like I'm trying very hard to find nice things to say about him?
