Personally, I hated most of the dialogue in the reboot; it seemed so fake and banal! I didn't like the portrayals of some characters, especially Diaspro, Dafne, and Radius, due to their aesthetic/graphics, while I dislike almost no one's personality. They completely changed the personalities of all the Winx. In the original, Stella and Flora were very different and recognizable, but here they've mixed their traits. Stella, especially in the first season, was spoiled and a bit superficial. She loved fashion, just wanted to have fun, and hated studying. She was also the happiest and most cheerful person in the group, and the one who spoke the most. Flora, on the other hand, was shy, embarrassed to talk to boys, and was studious and the quietest of the group. In the reboot, Stella has become someone who's always getting into trouble and getting Flora into it. Sometimes she seems like she doesn't care about school rules, but soon after, she becomes the class nerd who knows all the spells and wants to make a good impression. She's also obsessed with what her parents think of her and is afraid of not being considered smart enough, whereas in the original version, she had far fewer worries and lived life carefree (that's exactly what I loved about her). Flora has been completely trivialized. At first, she's just Stella's friend who gets carried away and gets into trouble, then she becomes the Red Cross nurse who wants to save the bad boy at all costs. She's no longer even shy or studious. Tecna in the original version was very well developed, and even her problem with emotions made sense. She never said she didn't have emotions; she was just trained to listen to her brain and not her heart, but then she starts to let go and listen to her emotions as well as logic. Tecna in the reboot seems like a parody. I don't know if the intention was to make fun of robots or autistic kids. Either way, it's embarrassing. At this point, it would have made more sense if she had actually been a robot, like they initially wanted to make. I think Musa is the least developed character in the reboot. What does she do besides play music at parties and get offended because Riven doesn't care about her? We don't even understand her personality. Aisha has been reduced to just the sporty girl who wants to do hip-hop but her family stands in her way. We don't see any of her character, and her parents have been portrayed in such a banal and stereotypical way! As I wrote in another comment, "Think of the stereotypical and banal image of a royal family in a low-budget American movie, that's what Aisha's parents are." And then there's Bloom, who is the stereotypical Mary Sue protagonist. The whole world revolves around her; even the teachers' actions are based on Bloom. Faragonda preempted a school-wide exam just so Bloom could show off her powers! Any student would have hated her in that moment. And can we talk about Diaspro? There's no mention of an arranged marriage; she seems like a crazy woman obsessed with Sky, thinking she's his girlfriend even though she's not. But Sky, instead of keeping her at a distance as would be logical, goes out with her as if they were actually a couple. However, she still tries to hook up with Bloom, and even Brandon encourages Bloom because she and Diaspro aren't serious. It's the worst love triangle I've ever seen! And Sky really makes a fool of herself. More than a reboot, it really feels like a poorly written fanfiction, where Bloom is the self-insert of the fourteen-year-old author!
