For those asking what PreCure is, it's short for Pretty Cure, it's start in 2004 and has been going since, it's pretty much what you would say the Kamen Rider/Super Sentai (Power Rangers) equivalent for girls. The only difference it's animated instead of live action, each series has a specific themes like butterflies,music,flowers,etc. The current one below is about sweets and animals. The reason Chris may like this is because of Megan and his whole autism and loving to see flashy things. Since it's made for young girls, the transformation scenes are over the top (more so than Sailor Moon) for example:
