Edit: Whoa, okay. I’m gonna clear things up right now. Top List, go.
Rainbow Rocks, obviously, it’s the best of the current four, and a lot of other fans think so.
2 and 3. Friendship Games and Legend of Everfree, they are really interchangeable in my opninion, because what one lacks, the other one makes up for (FG has the awesome soundtrack but Meh story, while LoE has the better story but lacking OST, in my opinion. I only have one LoE song I’ve listened to more than once)
The Original, yes, it’s not the best movie, or even the best thing to come out of the entirety of MLP, but I don’t hate it. Like I said, it was my introduction into the show, so I can’t hate it. I do acknowledge that it’s not very good and all 3 of it’s successors are in some way better. Someone can like a movie even if it’s not widely seen as a good one.
