Oh yeah Wesley was so dark, suspenseful and threatening
And I'll go on record to say that I actually liked Wesley. Not one of the best Trek characters ever, sure, but he had some damn good episodes. The First Duty, Journey's End, and Where No One Has Gone Before to name a few. Plus I don't think Justice is as terrible as everyone claims.
I don't hate Wesley either, but it's not like the handful of Naomi episodes in VOY stand out. DS9 had Jake and Nog hijinks eps. The series with the least amount of children was Enterprise.
I like the Naomi interactions with 7. Naomi is a smart kid and she seems to appreciate 7's complete inability to treat her as a child.
