There is no interpersonal conflict allowed in Gene’s vision of Starfleet. Oh they might but heads occasionally, but every episode resolves with everyone putting their differences aside to work as a team. It’s practically a cult mentality. Gene would not have let them write episodes telling those kinds of Dead-parent/Step-Parent/Oedipal stories. That doesn’t exactly excuse the bad writing of the Wesley episodes, but it does explain why the writing did not go to those places.
