Well, I really like all the characters, and I'm cool with all of them being main characters. I know some people don't like Starlight as a main character, but I'm happy with it.
I totally agree. At first, I didn't like the idea of Starlight joining the Mane 6, but after a while (not to mention her new, beautiful hairstyle ) I'm actually open to the idea. So I guess I'm happy with it too.
