TL;DR The show had such an interesting premise, it's a shame that the world building never occured and that the characters were never flushed out. This PowerPoint is rather dreadful. This show is a red, skip it. But go listen to the OP, it's good.
Raeliana! A Japanese anime based on a Korean web comic about pho-European nobility squables. What do the nobility want? What dark secrets will be revealed? Who is scheming and what are their grand aspirations? Well hang on to your seats cause we won't be answering any of those questions.
This anime is riddled with issues. To begin, the story, if you can call it that, starts out with a fascinating premise similar to Villainess but seems to take a darker turn, until it decides that taking no turns and not moving at all is a better route. 7 episodes in and I couldn't tell you who the antagonist is, what any nobleman wants, or even what goals anyone could shoot for. The show tries to seem secretive but, as demonstrated by the quick cutting of the only two plotting characters we knew, doesn't hide anything behind the curtain. It is merely one thing led to another with little world development, fewer antagonists, and less things to focus on.
Animation, you mean PowerPoint presentation. The animation features some select scenes of fun lighting but almost no movement whatsoever. It's not Twinkle Nora Rock Me bad, the colors are nice, but almost no one moves ever. The lack of animation, once you notice it, cannot be unnoticed. At least the backgrounds look ok.
Sound! The OP is super good, so is the ending song. Does anything else stand out? Nah...
Characters, spoiler? This show drops the politicking like a lead stone and immediately shifts to the most forced romance possible between Raeliana and Noah. The issue? There is negative chemistry between them. Honestly feels like this was written for young pre-pubescent girls who like guys who are edgy and Noah is meant to be edgy because... well... the show tells you he's edgy. I have no evidence to back up Noah actually being edgy. Ironically, the chemistry is so bad that Raeliana's character swings all the way from terrible to somewhat funny as she seems to be almost aware of how terribly dreadful the character interactions are. Those are the main characters, as for the other people in the show, we know that they exist and occasionally we are told, never shown, that they might be a certain way. The characters are all flatter than the animated world they inhabit.
Overall verdict: Despite an interesting premise, the show becomes bogged down due to its lack of a driving plot, boring characters, and burdensome PowerPoint style animation. What could have been an interesting story of intrigue, love, murder, and survival, became an awkward romance where no one's motivation is clear, events happen from convenience, and a plot that matches the animation style for smoothness. Regrettably, this show is a red, skip it unless dreadfully bored. But go listen to the OP, it's good.
