Ya know, with Happiness Charge Precure coming up and the characters are being revealed, I keep wondering what the character dynamic will be.
One of the things I always liked about the original Pretty Cure is its "Opposites Attract" theme what with Nagisa being an Outspoken, Pessimistic Sports Jock and Hanoka being the Polite, Optimistic Science Nerd and how they wouldn't really have the chance to be friends if it wasn't for the impending doom they have to destroy. There's some initial clashes of course, but by the end they're BFFs
The different Kinds of friendship are sort of an ongoing theme of course, and I like how each one tries something different each time. Some are stronger than others I think
Splash Star - Girls who met in childhood, were separated, and came together again without much initial conflict.
Precure 5 - 5 different personalities and ages, all sort of chosen by their leader. Like Futari wa, they probably wouldn't all be friends if not being drawn together by Nozomi.
Fresh - 3 childhood BFFs, go to different schools but are close regardless. Trials and conflict come when a 4th person enters the inner circle.
Heartcatch - Another Opposites attract. This time with more personality clashing with Erika's outgoing in your face attitude and Tsubomi who's just trying to break out of her shell.
Suite - Childhood friends but stopped their friendship due to a misunderstanding.
Smile - 5 girls that get along just fine
DokiDoki - Everyone is brought together due to their love bond with Mana.
I think that's why Smile and DokiDoki have felt a bit...hollow to me. There's not much to analyze between the characters.
I'm hoping the new season will bring more clashing personalities. When characters are drawn to each other due to their own personal conflicts and they have their opposite opinions, its more interesting to me.
