A lot of people are saying Applejack was acting out of character here, and I can see that. Personally, I just enjoyed the silliness of it. But, man, that monster scene in... hell? was just bizarre, and came out of nowhere. Applejack was badass, but that's one of the most nonsequitor action scenes I've ever seen.
@meetroid8: I personally didn't think she was out of character (of course, she's been shown to be over-protective of Applebloom even in season 1).
I love a good gag, but some parts were just a little too ridiculous and too over the top for my liking not necessarily because AJ is normally shown as the typically level-headed character she is, but it just didn't feel believable at all
I did enjoy the episode for the most part though, and there's some great fight scene gifs already.
Oh, right. That's been long time to go without seeing that side of her personality, though. I think I need to watch the first season again. It's been long enough that I'm starting to forget a lot of the specifics of the episodes.
