VOY: "Resolutions"
At this point in the series, Chakotay not only still has a war to return home to finish fighting (or at least thinks he does), but he has an entire crew of lost Maquis missing their commander, and he currently thinks Seska is carrying his son. At with NO hesitation, he giddily surrenders to the idea of living on New Earth with "Katheryn" for the rest of his life. His "Angry Warrior" story even spells out that he wants to spend the rest of his life as Janeway's subserviently boy-toy. Insulting to Chakotay's character. Not to mention an unhealthy idea of relationship to be pushing on the--let's face it--largely romantically-challenged Trekkie population. It's like watching a bad fanfiction, where Janeway is Mary-Sued like crazy. (Jeri Taylor was somewhat notorious for that.)
VOY: "Before and After"
I have such mixed feelings about this episode. Because honestly, it's a damn good episode. It's fascinating. But god, the Tom/Kes marriage is gag-inducing. It's far-fetched enough to believe that out of a ship of 150 people, the best matches for Tom and Kes after B'Elanna and Neelix stop being options is each other. But the way Tom fawns over Kes-- "I thought the day we got married was the happiest day of my life, but each day just kept getting better and better!"--Jeezus. Unless you interpret that as Tom just desperately trying to cheer up his dying, senile wife, and not really meaning everything he says. Otherwise, it sounds like a die-hard Kes stan wrote it.
(Amusingly, as soon as B'Elanna gets back into the picture, the episode does a 180, having her come up with the solution to Kes's time-traveling dilemma right on the spot, emphasizing how badass she is and how screwed Voyager was without her. It's like the first half of the episode was written by a Kes stan, and then a B'Elanna fan flew in to save the rest of the story.)
DS9: "The Darkness and the Light"
Brave, selfless Kira Nerys willingly and deliberately endangers the life of the O'Brien's baby, the one she volunteered to be a surrogate mother for, specifically to save said baby's life. (Side note; I'm very pro-choice, but she was like, half a week away from giving birth by this point; so it's a "baby.")
Worst of all, Kira gives birth in the VERY NEXT EPISODE. Ignoring how awful her attitude toward Miles in that episode looks after what she did to his son in this one, why the heck couldn't the writers have just waited until AFTER Kira's character gave birth to do the "Darkness and the Light" episode? I don't understand it, and it butchers one of my favorite DS9 characters.
DS9: The One Where Odo Fraks Himself-With-Tits
I don't know which specific episode in the Dominion War arc this was, and I don't care. All that matters is that Odo--the CONSTABLE of DS9--you know, whose entire career revolves around ensuring the safety of everyone on the station--decides to endanger everyone under his watch: the thousands of civillians he took an oath to protect, his fellow officers, his friends, his love interest Kira, and oh yeah, the entire frelling quadrant, and for what?
Sex.
With another Odo.
That has tits.
I'm not exaggerating. If you aren't familiar with DS9, Google "Odo," and then Google "Female Changeling." She is LITERALLY him with tits.
And apparently Odo's ego is so through the roof that he cannot resist himself-with-tits, even when everything he values and holds dear is on the line.
DS9 "Time's Orphan"
Keiko O'Brien was always a flawed human being. But here, she does/says something heinous. Her young daughter Molly has fallen through a time portal, and grown up alone in the jungle on an alien planet for like 15 years. The traumatized, Tarzan-ized young woman is reunited with her parents, unable to speak or control her rages. The O'Briens are told an EASY solution, that will undo this timeline and restore little Molly to her proper age, so she can live a decent life. And Keiko says, "This IS our Molly. We don't have the right to take these last 12 (or whatever) years away from her."
As an L.D. person whose parents ignored the urges of teachers and counselors begging to get me tested and treated, this hits me hard. Refusing to let your child experience full awareness and independence, because you want to make some philosophical point to the universe, is disgusting. I'll never forgive Keiko for that.
TNG "Relics"
The way EVERYONE treats Scotty seems very cold, for an old man that was just freed from decades in transporter limbo, who's just learned all his friends are long dead. But this old man is SCOTTY. It's like if NASA discovered Neal Armstrong frozen in carbonite, and none of the NASA workers found anything interesting or remarkable about him. Most ludicrous of all is Geordie, the engineer. Scotty should be to Geordie what Kirk is to captains.
Later in the movie "First Contact," Geordie wastes no time fangirling over Zefram Cockblock or whatever his name is. But he doesn't care about meeting Scotty?
