Fanfic 100/10
Reading the Guides is like reading a mystery, fantasy and sci-fi novel all in one. While it might not appeal to everyone, the author’s focus on adding as many layers to the plot, characters, scenery, backstories, and all the other aspects of the story is incredibly in depth and exceedingly articulate. Also, the range and cast of characters is a great example of representation that isn’t simply for the sake of diversity. That there are so many installments that are planned is phenomenal.
Fanfic 3/5
pros: - there is a lot of worldbuilding which is creative and interesting - if you enjoy luke & vader father/son fluff, you got it - if you're interested in content that depicts the imperials as sympathetic/explores the imperial culture in more detail this will scratch that issue
cons: - author is very wordy and it can get boring/hard to follow at times - characterization of canon characters is gonna be ymmv; personally i'm not a fan of luke in this fic, for example
overall i'd say it's definitely worth checking out, but if the first installment doesn't appeal to you i don't know that you'll get anything out of pressing on
Fanfic 110/100
I've never enjoyed a series this much. And to think they still have a way to go! At least six years, if we make add the numbers (one chapter per week, twenty four installements yet-to-be-published at the very minimum)!
I may be biased, but I love the Guides very much. Luke Skywalker has always been my favourite character, and the way Jack, the author, is writing him is absolutely breathtaking. He has kept his core true, while thrusting him in a very different path than the Original Trilogy gave him, and, if you flick through Jack's tumblr, you'll see this is just the start.
I can also say only praises of the amount of thought and work that go into each aspect of the Guides. Not only is Jack offering us a new path for Luke to follow, he's also creating a miriad of worlds out of his mind. He went 'canon is dead' and followed with it. If you want any example, there is none better than Tatooine itself. We get a whole new mythology to rival Fialleril's, and if you've been long enough in the fandom you know exactly what I mean. There is also all the subtle groundwork hidden in each sentence that makes each plot twist make sense. I believe there is no sentence written without any other meaning attached.
Of course, if you don't like this sort of thing, don't read it. In my case, well, I love puzzles, and the Guides may be the most complex one I've ever encountered, as it doesn't just deal with logic, but with the nature of humanity too.
