Just finished the book today. I woudl have finished it sooner but the writing style made it difficult for me to stick with. I often had to put it down after only a few pages, due to frustration. Once I hit the halfway mark though I was able to finish the rest of the book in 2 days.
I'll say this. It's the worst book I've ever read. Granted I have only started reading seriously the last few months, and have read amazing books like the Martian and Ready Player One. So it being the "worst" might not mean all that much.
My main complaints follow: There may be SPOILERS
1: Writing Style - Wedge tells Ackbar, Mon Monthma: "We have to do X,Y, Z" Things like that annoy me. The author uses a TON of colons and incomplete sentences. At one part there are two paragraphs contains entirely in parentesis. Consecutive paragraphs. And they were about the same topic. I don't see why they needed to be two separate paragraphs, nor why each of them needed to be completely enclosed in parentesis. Things like that distract me from the story and make me think about the grammar and syntax way too much.
2: Hollow Story - There is virtually no motivation for the people to do the things that they are doing. The only real motivation is money, a bounty hunter is going to share her bounty with everyone if they all team up and kill all the imperial bad guys.... It isn't "Believable". A Mother who's only motivation in the world is to be with her son and save him, abandon's her son at the drop of a hat and disregards her entire motivation multiple times in the story. The "Gay" character isn't gay until a single line in the last few chapters, and there's no reason for him to be gay, other than out of NOWHERE one of the female characters is like "Hey, do you want to have sex after this mission is complete?" and he says no. Hell he might not even BE gay, he might have been trying to let her down gently. Anyhow, it had NOTHING to do with ANYTHING and I would have rather him have a husband or something so that there was some reason to mention his orientation other than the sake of diversity.
3: Main Character X Dies. Next page you find out the author lied. - Author does this like 4 or 5 times in the book and it gets old quick. Explosion - and he lay there, dead. Next page :"Well I thought I was dead, but turns out I've just got a bump on the head". It it happened once I'd think it was clever. It happens TOO much. And when peopel DO die, it isn't even mentioned until MUCH later, "Oh yeah this person died 4 days ago BTW".
4: Doesn't feel at ALL like Star Wars .- Insert this story into any other setting and it's still a lame story that "works" anywhere. Nothing about it has much to do with "Star Wars" unless you consider people's backstory, which doesn't really matter.
5: Interludes - These blasted interludes are TOO MUCH. Almost every chapter ends with an Interlude after it. It is frustrating to feel like I have to read an entirely new story every 6 or 7 pages. And while one or two of the interludes are interesting, I found many of them to be forgettable or otherwise uninteresting. It would have been better to have maybe 2 or 3 interludes tops, instead of like thirty. (Don't have an exact count but it feels like thirty of them).
6: Lack of Legacy EU Tie-Ins - I was expecting at least one character from the EU to show up, or for them to name-drop someone. I know this is a weak gripe, but it's my last one.
Yeah matches the complaints I've read aswell, I've read some stinkers in the EU but they sound better than what you describe.
