When Hayley and Sarah are on Earth, Sarah is next to Hayley. When they're transported to the Warrior Dome, Sarah is behind Hayley.
It's middle-aged men who defeat the Basherbots, but when Monty and Victor arrive, the human group comprises previously unseen women and children and one young dude.
When the Ranger teens transform to fight Madam Odius, their line-up becomes the complete reverse of how they start out - from (left to right) Pink-Yellow-Red-Blue-White-Gold to Gold-White Blue-Red-Yellow-Pink.
Hayley apologizes for breaking up with Calvin. Actually, she only asked for space. HE broke up with HER.
It could be by luck, but Preston directly calls Hayley to shut off the satellite dishes, not knowing she's in the satellite room and not Sarah.
Sarah does not exhibit nearly complete exhaustion from her extended non-Power Ranger solo fight against the Basherbots.
When Mick was hit by the Mind-Control Ray, the effect was permanent with the ray no longer running. Now it becomes a matter of shutting off the satellite beam to return every affected person instantly back to normal. That's like destroying a hive after getting stung by a bee and expecting the stinger and its venom to completely disappear.
Perhaps, a matter of wording. Madam Odius' mind-control is deemed a spell, yet Preston the magician (really a sorcerer) is never, not in the slightest, brought into the matter to magically try to remedy it.
