Well, you can just let her watch one of more adventure paced eps or even better, ep that might be in her character and hope to success the roll. Sadly some people might still hate MLP even if they gave try (My mother while doesn't hate MLP:FIM, she doesn't want to watch it at all). If it won't work... there is always cupc... let's forget about that ^_^'. If it won't work sadly, she will never like MLP:FIS. At least until she will become less closed-minded.
