The animation overall is decent, but the transformations and attacks alone are very colorful and unique. The soundtrack also complements the tropical aesthetic of the show really well.
I didn't expect much going into the series, so I was surprised by the bits of lore and ideas that could have been great if developed properly. Unfortunately, the ocean theme of the show is highly underutilized. Watching the girls try various things is fun but plot-related episodes are scarce. The monsters are quite weak and on the occasions that they are strong, the characters get magically saved.
The characters are usually all together and their friendship is well-established, but there is a lack of character focused episodes. They have some unique traits and battle techniques, though. While I liked that this PreCure season tried to do something different with the villains, they don't really challenge the heroines in any way since their whole shtick is being unmotivated.
Overall, Tropical-Rouge is enjoyable when it comes to slice-of-life, but not so much when it comes to magical battles. I wish it had done more with its themes of the ocean and motivation, but it works quite well as a comfort show.
