I'm currently watching Heartcatch Precure. I've heard that all the Precure seasons are pretty similar, so I asked around which one people said was the best. They pointed me in the direction of Heartcatch. I'm not disappointed.
Loving the super powered fighting that's unlike anything I've ever seen in a Magical Girl anime, the dazzling visuals. Plenty of great character development. By episode 29 it's safe to say I would be pretty depressed if one of these girls died.
Heartcatch has a victim of the week thing going with it's filler episodes. Much of them focus on some character with an emotional problem that gets manipulated, turning them into the monsters they fight. On a really bad filler episode, the main girls can be on screen for only five minutes of the episode, fighting aside. Transformation sequences taking too long (almost two minutes) are another thing, good thing I can just skip those. Another thing that's exceedingly repetitive is when the monster of the week fights suddenly stop for this usual exchange.
Monster: *cries out the victim's problem*
Villain: *mocks the victim's problem*
Precure: *Defend the victim's problem* and if it's Cure Blossom, nine out of ten times she'll utter an annoying catchphrase, outlining what problem the villain is manipulating and going on about how her tolerance is at it's limit. Then the other one utters a similar line involving oceans.
At this point I can't say if I'd watch any of the other seasons, especially if they don't have the same awesome fighting as this one. Sadly I don't think this season's ever gonna get licensed. Only the first one has so far and there are a lot more to go...
