Keroro (2014)

Keroro(ケロロ Keroro) is a Japanese anime series, based on both the Keroro Gunso manga and its television series. It serves as the spin-off/reboot of the original anime, and even includes new characters and storylines. However, the plot remains the same. It ran from March 22, 2014, to September 6, 2014.

In contrast to the original Keroro Gunso anime where its episodes have a half-hour runtime with usually two 11-minute segments per episode, each episode in this anime has its runtime reduced to 3 minutes. And unlike the original Keroro Gunso anime which was traditionally animated using digital ink-and-paint animation, this anime is animated using Flash animation.

Plot
A pair of adolescent siblings named Fuyuki and Natsumi gets a sudden visit from an unusual frog, who later introduces itself as Sergeant Keroro from the planet Keron.

Bad Qualities

 * 1) Some of the characters have been profoundly flanderized due to the crew running out of ideas.
 * 2) * Keroro is stupid, lazy, and doesn't do anything special for plans.
 * 3) * Tamama is a bipolar freak who seems to have an obsession with his sergeant.
 * 4) * Giroro is downright edgy, uncaring, and shows little to no interest for Natsumi.
 * 5) * The only characters that were not flanderized are Kururu and Dororo since both of them are still in character most of the time.
 * 6) Awful, ugly, and poorly-designed realistic backgrounds that look like they were copied and pasted from Shutterstock.
 * 7) Poor grasp of the original source material: Most of the episode plots don't even follow the original storylines for where they were originally based (both the anime series and manga).
 * 8) Tons of animation errors.
 * 9) The human characters all have the same skin color (pale), making them look like they're the same person individually.
 * 10) On top of that, all the characters are badly-colored with overly pale, bland, and desaturated colors, which makes them all stick out very badly like sore thumbs over the realistic-looking backgrounds due to how overly bright they appear on them, hence making the relationship with the character animation and the backgrounds feel almost non-existent.
 * 11) The animation looks cheap and bland, even for flash/anime standards.
 * 12) It takes place somewhere in 2014, but since the series takes place in different timelines, the fact that it takes place in modern times seems rather forced and clichéd.
 * 13) Why does the alien invasion in Fuyuki's dream happen in the day instead of either afternoon or night?
 * 14) Sequel baiting: The end of the final episode of the series says that a new episode would appear next year (2015), but this never happened. Even worse, it also pretty much ruined the Keroro Gunso franchise, with no signs of it getting another anime series as of now.

Good Qualities

 * 1) Catchy theme song and soundtrack.
 * 2) Improved character designs that look closer to the manga.
 * 3) At least the reboot shows some charm that the original Keroro Gunso originally had.
 * 4) New characters are introduced.
 * 5) It got positive attention in Japan, and the old fans were glad to see the show come back after almost three years.
 * 6) The original voice cast returned, except for Fuyuki's original voice actress Tomoko Kawakami due to her very tragic and teary death after several years of battle with ovarian cancer.
 * 7) As mentioned in BQ #1, Kururu and Dororo are still likable characters as usual.
 * 8) Like the original Keroro Gunso anime series preceding it, this reboot tones down the adult/mature content present in the original manga in favor of making it a family-friendly show.

Trivia

 * 1) Mine Yoshizaki, the author of the series, went low tide from then and seldom has improvements. The only exception was the anime version of Kemono Friends, though it was greatly adapted by Tatsuki, and their cooperation ended in mystery.
