Time to say "on toodles" to "Brothers", though a few of what's still in this list are almost as irksome...
Oh brother, where do I begin?
Yes, it's a visual masterpiece where they swapped the bulb to make the bridge go all blue alert.
Yes, Brent Spiner hits a triple home run as three different characters, which alone keeps the story watchable even during its deepest valleys - the guy is seriously
good.
And yes, it's also the first episode to cannibalize on its own past in trying to find new plotlines.
Okay, one kid scares is brother and goes and hides. Hiding kid decides to eat some local veggies much like how you don't wander into the mall's courtyard to snack on those mushrooms without permission because you don't want to eat at Burger Slop that's right around the corner.
And while I appreciate the notion that people in the 24th century actually discipline kids, Jake is treated like he just committed a dozen first degree murders.
Uh, shouldn't the Enterprise be stocked or have replicator recipes for needed drugs since they're out there exploring new worlds with competent Doctors and all? Nope, they have to trot back to the nearest Starbase. And thankfully her bare hands' oil secretions won't adverse the kid in isolation there, since the magical force fields probably dealt with any microscopic cooties growing on them before she shoved them into the isolation chamber.
Why does Data need to convince Dr "I created his name AND also have a name as a pointless in-joke to Khan" Soong about Lore being bad and evil and everything when Soong dismantled and repackaged him up to begin with?
If Soong outright disbelieves Data's own discussions of Lore being bad because of what Lore did to the Enterprise crew: Attempted to commandeer the ship, kick his brother in the head and almost to an irreparable state, threatens crewmembers' lives, fires on a crewmember causing 3rd degree burns as she flails out of the room with her upper arm lit on fire and all... oh, pity
only Lore and not those he victimized, some severely so... Seriously, despite Soong himself dismantling the errant android over him frightening the colonists to begin with and he poohpoohs Data's own warnings as if he was the total liar? Oh brother... Soong's own emotional chip is more than haywire, Lore isn't having a mere "malfunction"...
Why would Lore care about all the time lost while he was deactivated? Androids can live forever if replacement components are produced. And given how evil he was to the Enterprise crew three years earlier, does anybody believe he would really let his creator diddle with his diodes? I doubt it.
If both androids are identical in hardware but only different in programming, which makes sense so far, how come Soong needed to make a special emotions chip to shove into Data's empty expansion socket, since Lore's socket would already be occupied with whatever emotion chip prototype was in there? Would Soong really program something into a built-in EEPROM and leave a cartridge slot available for future expansion? Otherwise, if Lore's chips are pre-programmed, why couldn't Soong just upload the algorithms and functions similarly and keep the expansion slot open for another 512KB RAM expansion or 68881 FPU? Something's not quite right...
Lore knows he's getting an emotion chip meant for Data. What does he believe it'll do for him? He knows he has emotions. He doesn't think he has any problems that need fixing. Even more potent emotions? Maybe he wants an analogue of an emotional disorder by having two emotional processors installed. Stereo emotions?! Would he really want to be stuck with constant, literal
ambivalence for the rest of whatever?!
And it was sorta obvious in "Datalore" that Data was not the imperfect model, though if Data is not to have emotions, his being astonished over what he was told... oh brother...
At the end, Troi says how brothers forgive. Forgiving is part of an emotional condition. Data ends the episode stuck in a loop because he has no emotions (unless the plot otherwise decides he needs to be astonished) and can't figure out the reason behind the concept.
((Then again, said chip is said to be irreparably damaged in "Descent", but that didn't stop him from getting Geordi to shove it in there for "Generations", for which it became fused (yet, despite such a process requiring heat, the surrounding circuits weren't damaged in the slightest) plus all the continuity gaffes that followed from there including being able to turn it off and on at will, or even later acting as if it never existed... ))
