Fun episode, but not my favorite though. I was suffering from some rather bad neck pain when it was on, however, so that definitely affected my ability to enjoy it.
Good points:
Rarity was a hilarious hypocrite (again). Her frayed relationship with Sweetie Belle is becoming one of my favorite things.
I loved the spa scene and seeing Dash's almost physical revulsion to girly frou-frou stuff. It's so rare to see the entire cast together being friends this season that I'll eat up any chance we get.
Trixie shout-out!
Smarty Pants callback! Very surprised they went with the fandom interpretation of Big Mac keeping her and fawning over her in private, but there it is.
Also, "Family Appreciation Day" and "Baby Cakes" callbacks. This episode was just loaded with continuity.
And, of course, Applejack's "Eeeeyup" and "nnnnnope," while Big Mac goes on a long, wordy rant. Good stuff.
The not so good:
Scootaloo confirmed for can't fly.
I think I see what people have been saying about the CMC not being so great when they're actually crusading. Aside from the fact that it made them do really mean things this week, there's a fundamental problem that the crusading often involves them forcing themselves to do things they don't really want to do in order to get their marks. That's a lot less engaging than, say, "Hearts and Hooves Day," where they do what they do because they like it. It is off-putting to see them be that obsessive to their detriment and everyone else's.
This might be my physical discomfort affecting my attention span, but I though the episode felt kind of choppy, in terms of how they ended up on staff, writing a gossip column and having the paper become a town sensation.
I wasn't too hot on the ending where everypony shuns the CMCs until they apologize. I know the point the writers were making, but some of this seemed really immature. Twilight's reaction especially of sealing herself in a bubble; and she was the level-headed one earlier in the episode! Ultimately, the crusaders are still
kids and everypony affected are adults. In real life, somebody would step in and have a talk with them about what's happened and enforce some kind of rules, not let them continue to run amok and act all hurt and petulant when they do. This one of the (rare) downsides to being a moral-driven cartoon aimed at kids; it was designed to make a point about school gossip, and so points out in no uncertain terms that gossiping hurts other kids and that's bad...but since the CMC are the only well-developed child characters on the show, the writers roped the Mane 6 into being expy schoolchildren, and it just didn't gel.
