-Rockhoof and a hard place was a funny episode, although some parts of the first half were a bit boring. Some people would find it unnecessary, and it kinda is. But if you're going to write an unnecessary story, at least make it funny. Kinda like the Flim Flam Brothers episode from season 2. Unnecessary, but funny.
-What lies beneath was... meh? I like the idea behind the episode, but I don't know. It looks like an ancient simulator instead of a challenge of the six students. It's not very funny, sometimes it's creative, and nothing more. And that ending would have been intriguing if it wasn't for some spoilers I've read.
-Sounds of silence was a good episode. I love the concept, the character design is kinda cool and the story is interesting. Some parts were a bit boring like the song, but it's cool. It might be my 4th favourite episode in season 8.
So, 3 episodes left.
Actually, _*two_*. Father knows beast and School raze.
