I love this novel totally, I'm not a DC fan and this is the first DC fanfic that has trully gotten me hooked up. Let's Go.
Writing Quality: Nigh perfect English, the right amount of words in every paragraph, the contexts can be understood perfectly in every escenario.
Stability of Updates: I'm going to give this a vote of confidence as the last chapter was 8 days ago, I just hope this won't be dropped because it is awesome and it looks not too far from reaching a conclusion.
Story Development: You feel the story is moving forward, there is a finish line on sight unlike most fanfics and I'm desperately waiting for MC to reach it to know how will everything unravel.
Character Design: Perfect, I like MC despite what most people will say, he's human and he shows his humanity, most people try to make MC do things they themselves wouldn't do if put in the same situation. I love the girls, they're too cute and unique in their own way, especially Harley xD.
World Background: Perfect, proper descriptions are given in every scenario and MC goes and comes across america multiple times not staying all the time in one place.
Now my personal opinion, spoilers ahead:
I love this series/novel, as I said before I'm not a DC fan, be it as it may, I just don't identify myself with any of the two sides of DC. Batman is too dark for me and superman is too light for me, I'd probably go for the flash but I don't like his ideology just his powers. Whatever going back in context...
While reading this fanfic you will feel this distinct feeling that everything that you're reading is separated from the actual DC universe. Is like the author made a story of his own only using the locations and backgrounds of the characters in DC.
That scene when they went to the penguin and Harley almost betrayed them got me so hooked that I was like hell! I don't know if that was cannon or not (probably wasn't)? But I totally loved it! Have Harley almost betray them because of her heartache and that kick he gave Diana, off I felt all that and I loved it all.
This is a fresh romantic novel that takes you outside all the usual complicated politics and schemes that usually go about DC, things happen but rather than being the result of humans ambitions and the like, it is rather done by people's feelings of love and hatred, making one be able to identify oneself with them more easily different from what you would normally in DC as you know none of us is a multimillionaire as to feel identified with them in that regard.
Whatever it may be as I might be just speaking nonsense as I don't know much of DC, the point is that I enjoy myself more reading this one than other more politics-focused DC fanfics around, I even enjoy it more than those smut ones that are all around and about.
If I ever found a flaw here it would probably be Alice was that her name? the Housekeeper and OC. Her development as a character is too surreal, but then again she's an OC, the only way to keep her at the same level of the other characters whose background story is that deep in itself as it has already been written before, is to make mayor impactful events around her in the short while, so I won't decrease score just because of her, as she's way better OC than most I've read of.
The last point is about what most people complain that is MC's personality.
I really have to congratulate you here author as this is the most original and realistic transmigration sequence I've seen apart from probably Spirit Cultivation? MC was trash... Did he stop being trash just because he got a superpower? not and that's how things are, the things that are given to us don't change us, we change ourselves to cope with what comes to us.
If a narrow-minded person won the lottery then he'd probably use his narrowminded to spend the money the way his rubbish mind allows him. And that's what happened with MC, he was a heartbroken neet, what makes you think that just because he got power, he will stop being that? When he got something to motivate himself with, he stopped it and that's the way it should be. Did he stop a bullet for a woman? I'd probably do it as well, regardless of if I knew DC or not.
I love the harem, Harley and Pamela are lovely, I like them being villains because they changed, they're no heroes but they're not evil either. A hero that doesn't want to get his hands dirty is no hero.
Greetings author and I hope you don't drop this masterpiece.
