What bothered me:

- The Game of Thrones reference was the most unskillful and tryhard reference I've ever seen in MLP. I could sense the badum-tshh pause for the expected laughter.

- Yet another Wilhelm scream soon after. This is starting to look like an obsession. The sound design is really getting crude and in-your-face. They need to get out of their head and practice some more sensitivity for subtleties.

- Oh, a song again. A mediocre uplifting song about sabotage. This felt like a quantity-over-quality approach. Less can be more.

- Tank's voice acting was none. While it was just yawning, they could have imagined what a turtle's yawn would sound like. Instead, it sounded exactly like some random adult male non-actor yawning. This doesn't fit with the fact that Tank doesn't talk, because the voice totally suggests that he should be able to.

- No consequences at all for the sabotage? Does she have diplomatic immunity or something? (Probably time constaints, considered of secondary importance to the episode. But even just a brief hint at it would have been better than just acting like nothing bad happened. That together with her weird counter-productive behavior during the winter work not even being noticed by the other ponies felt very odd, like the episode was focusing too much on Rainbow Dash being the star and story and forgetting the impact on everything else.)

What I liked:

- Various character interactions. Not all of them, but the episode had some minor highlights. I liked the one with the name confusion. It got me confused at first, too, which is nicely involving and thus skillful.

- The general message of the episode is very valuable.

- Fluttershy

Overall I found this a mediocre episode.

It had Fluttershy though.
