Nothing agianst the actor. I hated Wesley Crusher... Utterly despised him as a snotty little *****. He was spoiled, special, loved, and everything I wasn't growing up. He was so Mary Sue as to be married to himself. He was that one kid I would want the teacher to look away from the class for a moment just so I could punch... Hard!
His writer should be shot in the hand and never allowed to work again. (Not literally only metaphorically.)
Most of the Klingons in later Trek TV bothered me.
Loud, blustery space-jocks who thought they were really impressive and scary when, typically, they weren't.
In general, they used the word `honor' to justify any and every action that the plot required, and they were easily manipulated into stupid and/or unwinnable battles with a few strategically-placed and totally-transparent insults.
I just found it really hard to believe in the later-series Klingons; that they actually represented a functioning culture and a viable galactic political state.
In Star Trek Online:
These days, I really dislike Captain Shon of the Enterprise-F, because his "worthiness" for that legendary command seemed so contrived to me.
He was a virtual (pun intended) nobody in the STO universe, until the last featured episode spent signiificant effort trying to "sell" him to the player base.
I realize random ship assignments happen in real life, but Star Trek is an ongoing fiction, not reality.
A storied starship deserves a storied crew, and in a game where characters like Akira Sulu and Miral Paris have already intersected with players' careers, Shon seems completely contrived and unworthy to me.
Oh, I also loathe Franklin Drake, but then, you're /supposed/ to hate him.
