I was in high school when TNG premiered, but IIRC what cheesed me off most about Wesley was his eager-to-please disposition and what felt like his frequent saving of the ship and his interactions with the senior staff. It wasn't that I was jealous; it was that I thought it was flat-out unrealistic. Where were his friends? How did he spend his time when he wasn't playing Acting Ensign? Are there really teenagers who act this way?
As someone who spent more time around his teachers rather than his classmates when the option was available I never found it particularly odd (although IMO both Nog and Seaquest's Lucas Wolenczak were better at this). However, I do agree that Wesley's character would have been better served by showing more of his interractions with his peers or even other junior officers (What relationship if any did he have with Ogawa, Gates, Jae, Wallace? Did he and Taurik ever meet?).
I think there were a number of pre-TrekLit novels that did a better job with his character than the series often did (The Eyes of the Beholders by AC Crispin, Perchance to Dream by Howard Weinstein and Q-in-Law are three that stand out as having a decent bit of character time for Wes in a more realistic way).
