Yeah, I only really liked one of the cutie mark crusader eps and that was the origin of the main cast's marks.

Most fans say Over a Barrel and Pinkie Keen have kind of weird moral things going on too. Like Buffalos=native Americans which I thought was rather blatant.

And the other one which gives Pinkie powers and focuses on skepticism and having faith and weird almost pseudo religious connotations. But I'd like to think that's not what they were really going for. :\

(These eps did give us Braeburn and Little Strongheart though. And Braeburn is totally fly.)
