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.

YMMV: MLP: FIM S2 E15 "The Super Speedy Cider Squeezy 6000"
This episode appears to have a "big business is evil; 'mom & pop' organizations are good" until you remember that Sweet Apple Acres is just one "branch" of the Apple Family business. They have farms all over the country in contrast to a company that consists of two brothers and their car.
"It makes more sense to trust someone who has a track record for trustworthiness and good work, rather than some fly-by-night outfit that promises you the sun and the moon."
Ho Yay: Rainbow Dash breaks into Fluttershy's bedroom before dawn just so they can get cider together. When She rips the blanket away from Fluttershy, the latter covers up her chest and gives a big blush (pointlessly, it must be said).
Idiot Plot: If either the Apple Family or Flim and Flam had had even an ounce of business sense, the entire thing could've been worked out to the benefit of all involved in roughly five minutes. See What an Idiot below for the specifics.
Nausea Fuel: The Flim-Flam Brothers' nasty cider at the end, with whole dirty apple chunks floating in it.
Older Than They Think: A pair of "new" background ponies (One with a wrench for a cutie mark, and one whose cutie mark appears to be Thor's hammer) have caught the interest of some fans and appear to be on their way to becoming Ensemble Darkhorses. They appeared as early as "Applebuck Season", but this might be the first time they've been shown with visible cutie marks.
Strawman Has a Point: When the Apples are protesting that Flim and Flam's quickly-made cider can't compare to the deliciousness of their lovingly-made cider, Rainbow Dash and the others who missed out (at this point acting as antagonists) counter that extra-delicious cider is no good to them if they never get to drink any. Which is... absolutely correct, cider that's just "okay" that you get to drink is better than cider that's amazing that you never get any of. Especially since Rainbow Dash was so desperate for cider that at one point she eats dirt.
Unconventional Learning Experience: You can get an awful lot of Econ 101 out of this episode regarding advertising, supply vs. demand, quality control, public relations, pony resources, artificial scarcity, effect of competition on market conditions, disadvantages and obtuseness of a monopoly, and the concept of inferior and normal goods.
Not to mention the effects of (early) mechanization and industrialisation on pre-industrial professions.
Flim-Flam Bros., did you really think it was a good idea to sell your badly made cider to the customers at the end of the show? Even worse, since they had some early barrels made from the best apples which probably would have been decent enough to serve. Depending on how you saw the townsponies' actions in the end, it might not matter if they used the decent batch or the crappy batch.
Why did you agree to let the "honorary" family members help the Apples? You were out-producing the Apples 3 barrels to 1. Then they asked to be able to double their manpower. While you couldn't expect that to increase production as much as it did, surely you could have realized your advantage would be reduced to an uncomfortably small margin. Pride comes before the fall, you know and you still could have salvaged a deal if you could eke out a win with 9 ponies producing cider against 1 machine.
The Flim Flam brothers getting competitive in the first place. The machine fills a niche that really needs filling. Had the brothers tried to work out a fairer deal with the Apple family, they could have landed themselves a neat profit.
By the same token, if the Apple family made any effort — any effort at all — to haggle with the brothers.
If you take an uncharitable view of her Honour Before Reason approach then Granny Smith betting the cider-selling rights to Ponyville and putting her livelihood in jeopardy. She hadn't even consulted Applejack and Big Mac on it, and the two of them looked like they had reservations over the agreement.
The Woobie: Thanks to given circumstances, Rainbow Dash comes off akin to the Trix Rabbit. Except at the end, she kept getting denied just one mug of cider.
