July's Manga

There's a lot of villainess isekai out there, but this one is probably the most insane one that I've read. You forget that she's an isekai'd character because she's completely into her role, playing the evil woman she is supposed to be. It's very unnerving to see, as I can't imagine someone who is not part of the original world acting so in tune with a person that was not them. Sure, you can say that she's experienced everything the original Roxanna experienced, which warped her, but I don't think it's possible to fall so completely in line with the entirety of it all. Yes, the whole Agriche family is batshit crazy, but she doesn't need to be, since she knows how it will end for them. Yet she follows their terrible ways almost entirely, the only exception being that she's saving the prince of the other family to avoid a disastrous demise.
The webtoon tries to paint her as intelligent, but seeing that she reincarnated into this body from when she was a baby, I don't think she is all that smart. She didn't figure out any ways to thwart the schemes in her own family, and she let her brother die, knowing it was going to happen, and not doing anything about it. If she had isekai'd into this body more recently, I'd commend her, but as such, she seems like she didn't take full advantage of her precognition about future events. Her attempts to twist the actions of people around her are half-hearted, and more emphasis is placed on her poisoning herself and controlling poisoned butterflies. Granted, she has some great moments here and there, but I don't think she's a strong female protagonist, at least from what I've seen from her so far. There's a lot of missed opportunities, and she lacks agency, which is why the pacing of the story is slow. She wanders from place to place and often passes out from poisoning herself, but she doesn't let anyone else into her plans. She also hasn't shown any real ability to manipulate people, other the stupid half-sister, which was actually done by proxy by her half-brother. The father and older brother are puppet villains who do nothing except to act scary and serve as menacing fake obstacles, since they're only around to conveniently appear to hinder her plans.
The art quality was rather inconsistent in the beginning, but got better and better with new chapters. Character designs are striking and memorable, it's pretty easy to distinguish who is who. The artist makes great use of the webtoon format to make very flowy panels, and the execution is just spot-on.
Overall, there's too much dichotomy with the evil family vs. the good family, and it's just unoriginal. The female lead is not a sympathetic character, despite the author trying to make us give her pity points whenever she faints. The reason is that she doesn't have someone she cares about in this world that humanizes her (not counting the prince, because that's plot-related), and she does everything of her own accord, she's not actually forced to do all these bad things. This is also not the story in which an evil character slowly comes to change themselves by being shown love either...and if that was indeed the goal, that wasn't a real attempt on the author's part since the focus just isn't there. There are some good ideas here, but also plenty of flaws. However, this is one of the better isekai webtoons that I have read with a decent female lead who isn't head-over-heels in love all the time.

This webtoon has some weird medical magic going on, but I'll suspend my disbelief for a bit. I don't believe an A.I. can be better than a doctor at diagnosing diseases, unless it's a simple condition. Even in the example given, the A.I. had incorrectly diagnosed pneumonia instead of tuberculosis, which can be a deadly mistake. The professor who explained it waved it away as human input error, but this diagnosis could have just been determined by humans instead of inputting so much material for a computer to process. It takes far too much time and effort to file the various lab results and symptoms, when as a doctor, you can reach a diagnosis more quickly by observing, questioning, and touching the patient. It would be helpful if A.I. was used in conjunction with doctors to further speed up the diagnostic process, but it's impossible to just rely on A.I. alone for this. The doctors here all act extremely questionably and should not have even been able to practice as doctors, because of their complete lack of empathy. Even the main character is not likeable, because he instantly brags about how smart he is when he's introduced, saying how he's the top doctor in his school, when he's only in the first year of residency. They go about doing very strange things, such as putting him on a ventilator and taking him off of it when his lungs hadn't been damaged in the first place, they forcefully wake him up to question him before he's fully recovered by cutting off the pain medication, and they don't run tests on him when he's awake to see if his mental and physical capacities are normal. Also, did the A.I. just make him have permanent hallucinations, because it's a floating chibi figure that only he can see and hear, and that's rather disturbing. At least the art is quite decent. Hopefully it gets better from here.
