Keroro Gunsou Movie 4: Gekishin Dragon Warriors de Arimasu!

It isn't the worst Sgt Frog movie for sure. In fact, it's my favorite out of all of them. First of all, you don't have to watch all the previous movies or the whole TV series to understand it. The characters are introduced right in the beginning, although I'd recommend watching some of the episodes first to get a hold of what Keroro Gunso exactly is. In short, it's a story about alien invaders from planet Keron who want to invade the Earth but end up befriending its inhabitants. But you probably already know that if you're here. As its title says, the movie is about thedragon warriors. Or rather, our alien frogs turned into destructive dragons thanks to the Dragon Tails and one of the human characters. The plot revolves around the Hinatas and Keroro going to France to stop the mayhem happening around the world which is caused by the once cute frogs now turned into these huge creatures who are out of anyone's control. I won't say anything else since I want to keep this review spoiler free. I have to say, it's a really nice looking and well animated movie, just as the rest of the entries in the Sgt Frog CMU. The fight scenes with the dragons are fluid, and the cuteness of the Keronian invaders is captured just well. Overall, it's a very enjoyable movie to watch if you want to relax. You have to remember that its target audience are children, so nothing gets too scary or violent and despite all means, everything ends well.
