@@shoyrumaster11, I see your point there but for me it's kind of... reversed. I think we can all agree that the first movie as a whole was horribly written. But, despite that, there are many Twilight moments to be found where she's trying to adjust to the human world. And, at least in my opinion, they were good. I'm not saying that movie was great because then I'd be lying but, at the very least, it did have some good moments.
As for Rainbow Rocks, by that time, Sunset Shimmer had become had regretted her past actions and was trying to find forgiveness among the CHS students. It's unquestionable that the movie was about her and not Twilight because that was the point of the franchise in the first place. Personally, I think she could have had a bigger role but, considering that it was Sunset's time to shine, I have no complaints.
Now for Friendship Games. I'll try not to go off on this one. Friendship Games was... a disappointment for various reasons. One of those reasons was that the pony princess who was in the human world the other times was now gone and replaced with... Sci Twi. I really missed her and now she was being replaced with this girl who was annoying obsessed with magic and who knew nothing of it. Yes, I did feel a tiny amount of sympathy towards her when being confronted with Principal Cinch but that sympathy faded away very quickly. And it angers that the movies have become about her and not Sunset, the one whom they were meant to be about.
