These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Power Rangers Lost Galaxy
Asspull: Nearly all the Rangers' weapons and gear are given little to no explanations as to how they got them, though most of them have at least some explanation. The Quasar Launchers take the cake, however, simply appear out of nowhere with no background story provided.
Complete Monster: Deviot, in a show full of villains with standards, had none. He was a manipulative, treacherous Starscream who would cheerfully throwaway his men's lives, thought brainwashing was a useful tool, and had no loyalty to anyone. When Scorpius wouldn't allow him to enter the cocoon, Deviot arranged for his death. When Trakeena, and not he, inherited control of the army, he sends two of his men to kill her; when she survives the assassination attempt, he kills the assassins to cover his tracks. He later brainwashed Loyax into fighting the Rangers, leading to his death as well. When Trakeena finally does enter the cocoon, Deviot ambushes her, and fuses with her. The absorption of his evil soul drives Trakeena completely over the edge, leading her to murder her mentor, Villimax, use her men as suicide bombers, and try to regain her human form by stealing the Life Energy of others. Totally untrustworthy, and out only for himself, Deviot proved that on his own, or influencing Trakeena, he could do more damage than any other villain in Lost Galaxy.
Also, in regards to the above scene with Trakeena and the wrench? The guy is Damon, whose actor later married Trakeena's actress.
In Power Rangers in Space, Karone, when she was still Astronema, kidnapped Ashely and impersonates her to destroy the Space Rangers from within. After that plan fails, she scornful exclaims, "I wouldn't want to be a Power Ranger anyway!"
Jerkass Woobie: Trakeena when taken into account that turning into a monster that had to be destroyed wasn't of her own choice at all and she was dragged into it by Deviot.
It Gets Better: Like most Ranger series, early filler episodes may put off new viewers, but, when the Magna Defender shows up, the show gets really good, and, moreover, for the most part, it stays good.
Like You Would Really Do It: Yes, this is the first -and thus far only season- to show us the onscreen death of a Power Ranger. Yes, it was a factor of Real Life Writes the Plot, but after 6 previous seasons where Rangers would survive every attack thrown at them, even when they were unmorphed, it came completely out of left field.
Trakeena killing Villamax in the Grand Finale. Villamax refuses to open fire on a spaceship filled with civilians, but Trakeena is hard-pressed on it. Trakeena then lays down a Curb-Stomp Battle on Villamax and kills him.
Vindicated by History: Inverted. It used to be known as one of the best Power Rangers seasons at the time when it first aired but fans becoming more aware of it's flaws and having morepopularseasonssince leaves Lost Galaxy in a strange middle ground, considered better than average but not well liked enough to be a fan favorite.
That said, it does still have many fans who consider it to be one of the best seasons of the show, likely due to it having a slightly darker tone than most of the subsequent iterations.
What an Idiot: Yes, Trakeena framed Treachoron, but does he seriously think that killing the Boss's daughter is a good idea? Not that it matters as he dies before Scorpius ever found out he attempted it.
