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 Light Speed Rescue
Complete Monster: Queen Bansheera; even in shows for adults, you'd be hard-pressed to find a worse boss. She has five main minions, and she's responsible for the deaths of four of them, and almost kills the last one, draining the life from one, blowing another to smithereens simply for being in the way, erasing the minds of the last two, Diabolico and Olympius (Her own son), forcing the Rangers to kill them, leaving only one, who remembered right before Bansheera killed him that he prepared an attack on the Aquabase, sparing his life. She's the only Power Rangers villain to get a Fate Worse than Death, as she ends up falling into the local Hell equivalent to be tortured for all eternity (or at least had her soul ripped out by demons. Oh, and the one who finally defeats her? The demon who performed a Heel-Face Turn, Diabolico, the only one who seemed to realize Bansheera was pure evil. Diabolico was the Big Bad at the beginning of the season. Bansheera was just a Bigger Bad at this point. She was that evil.
There is also the theory that says that the Rescue Zords were built from or reverse-engineered from the wrecks of the original Rescue Zords. Supposedly, this was the writers' original plan, but nothing's ever been outright confirmed on the matter.
Moral Event Horizon: Queen Bansheera does truly horrible things. She crosses the line when Olympius, her son, ends up stuck in the local equivalent of Hell; she opts to leave him there for being useless enough to get stuck there in the first place, and seems to take perverse pleasure in doing it, too.
Never Live It Down: No matter how many badass moments Carter had, two things stick out amongst fans: using his blasters and his dull personality. For the former, this criticism was unfair in "Forever Red", where the Cogs he faced used blasters as well, and he was smart enough to use his own weapon.
More of a case of Fan Dumb than anything. Why would he NOT use his blaster? Especially as part of a militia.
They Wasted a Perfectly Good Plot: Dana is the Captain's daughter, she is the most knowledgeable of Lightspeed of the 5 Rangers. She is not chosen to be leader. Never once does the show actually address this issue or Dana feeling resentment or hurt. Mind you, Power Rangers Wild Force and Power Rangers S.P.D. would make the "Ranger more equipped to be leader, but isn't" into character plot points.
Mis-blamed: In regards to Carter, it's not his fault that his Sentai counterpart didn't use a sword. There weren't even any swords in the arsenal or toyline! Go Red used a gun, so the Red Lightspeed Ranger uses a gun.
Anyone realize how stupid it is for a character to be hated for being Blaster Happy?
Not to mention, thanks to Linkara's review both Carter and the series' image overall is improved (though this started happening BEFORE Linkara's review). He points out how Carter Grayson may be dull but was a badass firefighter before being a ranger. While many fans disliked that Carter went for his guns first, Linkara loved that aspect because it made him one of the more Combat Pragmatist red rangers.
