I would've been fine if it was just a few times, but it doesn't need to be in nearly every episode.
The "Pinkie exploding," and Twilight "cracking apart" gags probably would be funnier if they were one-time gags too.
I love cartoony visual gags, (grew up with Looney Tunes, Tex Avery, AOSTH, Ren & Stimpy, and such) but they could come up with better ones, or some classic ones. @WyrmSpawN
Well, PL isn't meant to be a serious show, and debatably there are plenty of FIM episodes where a character like Rarity is a bit Flanderized for comical effect. (And that's not just something in later seasons, I remember Season 1 exaggerated things too for comic effect, especially before characters got development. Like Fluttershy literally being afraid of her own shadow, and such. In fact, it's funny fans used to complain she was "too wussy," now fans are upset she's "too assertive.")
