I've been trying fics from the front page. I would derec
Delenda Est - Harry Potter
Somewhat promising (thought Bellatrix/Harry Potter is normally a warning sign of bad fics). Technically competent but a lot of issues. Decent, but not best ever.
Whitewashing of the Blacks and Pureblooded elite that caused the whole mess.
Which causes the issue of the pieces against Voldemort to assemble too fast, meaning the Author had to do the time skip forward to stop them just dealing with him.
Harry and Bellatrix not knowing about Horcruxes as a plot element is just discarded. That could have really messed things up, but instead, they just find out anyway and set out to eliminate them just like nearly every other fanfic.
The caginess with allies is for no good reason and they walk into incredibly dangerous situations with no plan for if they fail. Which is particularly galling after they got time skipped and lost decades of the fight, letting Voldemort run free. Not that he uses the time to really do anything.
Really everything after the time skip forward is a major quality step down.
Bellatrix is redeemed way too fast. It is very hard to square this fics Bellatrix with the canon one, which is the one we supposedly have at the start. Fanfic authors are way too attached to making every good character like muggle stuff.
Bellatrix and Harry are super amazing duelists. I get some people are annoyed by canon going from he is an above-average talent to just an idiot who wins by luck. But fanfics go too far in the other direction way too often.
Also, derec
Burn Up - Worm
The writing really did not work at all for me. Been a couple of weeks since I read it, so the details have already escaped me, beyond me not really liking it and almost quitting reading a few times. Which also isn't a good sign. I do remember quite a few moments just felt like direct fan service, like the continued clothing stealing.
