Didn't get #3 and #4. The former (Sirens) is supposed to be bad, while the latter (Nightmare Moon) is supposed to be OK but I wasn't interested in it.
FIENDship is Magic #5 was pretty good, outside of how odd it was that Chrysalis was responsible for all these things and even encountered Celestia multiple times yet only seemed to be recognized by Cadance in "A Canterlot Wedding", and how dumb Twilight was in the end. Chrysalis' plan would have been thwarted if Twilight levitated the book in instead of reaching into the room. I'm fine with it being revealed that Chrysalis is also long lived. Other than that, the art was as good as always, especially during Chrysalis' origin flashback showing that she was always this way, there was a nice creepy atmosphere in the present, and there were nice gags, especially Rarity's story.
Reality is only for those who can't handle Star Trek.
