To start on a good note, the story is fairly well written. The dialogue (though it can be a bit wooden at times) is generally solid enough. The author does a good job of describing his scenes and does a very good job at providing vivid images of what is going on. It's a story with another overpowered Harry. He doesn't exactly have any weaknesses that have a significant impact on the story. It makes it a bit boring when it never really feels like he will be hurt. The worst part about this story is how the female characters are written. They're all virtually incompetent, unlikable, or one-dimensional. Bellatrix is a terribly written character in this story, as is Andromeda and Walburga. They lack depth and it is frustrating to read. McGonagall is portrayed awfully here. The obsession that Bellatrix has with Harry is something out of a teenager's fantasy. Towards the end of the fic, there is an event which makes me dislike the author even more for how he wrote Bellatrix and her story. Without spoiling anything, the way that the author treated Bellatrix in the last few chapters was quite despicable. In reality, the story is not. It is limited in scope (a good thing), and it wraps up its major plotlines nicely. It is dragged down by the author's poorly-written female characters, how overpowered Harry is, and the fact that the author never wrapped up the major subplots. I'd still recommend reading it if you are interested in a time-travel Harry story, but don't go in expecting it to be as amazing as some reviewers on FanFiction claim it to be. Unfortunately, the author passed away in August of 2018. He has a published story available on Amazon called "I'm Only a Freshman! (I'm Not a Super Spy! Book 1)" under the name Jonathan McCready.
This fic has great fights - some might even say one of the best in fandom. Harry is inventive and utilizes basic spells, as well as his environment, to the fullest. It's what comes in-between that's a problem. What took place after Harry's first fight? - He was interrogated by the Aurors, explaining what happened. - Bellatrix reported to the Knights of Walpurgis, explaining what happened. - Moody reported to Dumbledore, explaining what happened. - Bellatrix gave her memory to her family to be viewed in a pensieve. - Blacks contacted Potters, explaining what happened. Of course, everyone was very, very impressed. And the reader was very, very bored with the recounting of the same details for the fifth time. As a side-note, the fic would be a lot more readable if the 706 instances of "stated" would be replaced with "said".
