Medical Return

Maybe a 7/10 story without the flaws. But with how badly it's done, and this much focus on the drama... yeah, no thanks. The spiritual return/regression part that the author is focusing on is the weakest point of this story, too.

The MC has too much power at some point so everything goes his way and the story gets boring.

If you wish to read, only go up to his internship. Afterwards, it goes all mary sue. Most characters are treated as fans or critics. His superiors who aren't against him are his fans, praising everything he does. His critics do nothing more than object. The antagonist clearly has signs of problems, but the MC intentionally ignores the red flags. He never tries to understand the antagonist, not to forgive, but to figure out how to prevent these issues because he benefits from the problems. By the end of the internship, entering his residency, I started to dislike him. The author attempts to portray him as a saint who does no harm, but it's no better than praising McD for not hiring the worst teenager. By the time he was in the USA, he makes powerful connections with people in power. And when he returns, everything gets swept up under the rug way too cleanly. Then they try to make us think the MC will resolve his relationship with the antagonist. Really, just felt like the author ran out of steam and just had to keep hammering out chapters. If you really want a good medical drama, watch Scrubs. Dr. Cox is way more interesting than the MC, and John Dorian does a better job of showing the life of an intern.

The start was awesome ! Our MC is a genius but got no adversity until one point but It wasn't that great. Ending was unsatisfaying af.

I use to follow this series from almost the start. The MC went an bit over the top on some stuff but it was more or less bearable.

After a while there started to be more stuff to criticise, but after reading the end ... it all felt like a waste of time. As someone with various friends that studied medicine I really hated the ending. People without vocation make it difficult for the rest and it's even more frustrating when we see how his couple ends as a house wife ...

Though as a Korean reincarnation series I should've expected this ending ...

The MC is overpowered in a fairly believable way.

The story is interesting & move along fine.

The antagonist is hard to really appreciate. The situation around the antagonist seems strange and the lengths the antagonist goes with certain attempts to destroy the MC while seemingly unable to do anything are not that believable.

Overall though, many sweet and/or fun and/or thoughtful moments and fairly good art

Medical Return is a decent reincarnation story with a believably overpowered protagonist: instead of superpowers, he has a lifetime of medical experience and training.

Some weaknesses of the story:

The main antagonist is depicted a bit weirdly (he gets screwed over by his upbringing, then once more by the protagonist's reincarnation). There's a love triangle that takes too long considering how little it ultimately matters. There's at least one case of a literal deus ex machina (c87). And crucially, while there's lots of medical terminology, you rarely ever see medical techniques actually performed - at the very least, scenes in the operating room almost entirely focus on the doctors, rather than on the surgeries.

Also, the antagonist continually commits crimes, but no-one can do anything because "there is no evidence". So they're all supposedly perfect crimes, but the story never puts in the effort to show how the antagonist could possibly accomplish them. (Contrast this with Monster, which goes to great lengths to show just that.) And yet the very same criminal continually drops suggestive hints in his conversations. So he leaves no evidence so he won't get caught, then gives hints so he will get caught?_?

And finally, there's a brief Americans-hate-foreigners or Americans-are-racist story arc. This is not the first manhwa to do this, and I just find the trope tiresome. I'm skeptical whether Asian countries are any better in this regard, and would furthermore claim that the existence of this story arc and how it depicts people from another nation is evidence to the contrary. (Speaking as someone who's from another continent altogether.)

it started very well, but went downhill when MC forgives the villain and becomes friends with him.
but the villain poisons the MC, even after becoming friends with him(he helds grudge against him, later it revealed villain is psycho in progress)
MC is denser than the average your Japanese protagonist, mind you this is reincarnated story.
after 30 chapter MC starts to annoy he acts as clueless teenager.
story losses it originality and follow common Chinese troupes like mc save random homeless dude only it turned out to be a big shot and rinse and repeat it
