It was... Alright? I guess it gives a lot of now useless information but is interesting enough. You learn about some of the backstory of Palpatine, which is neat, but how much of it is and isn't canon is mildly confusing.
Cut out 90% of the debates on the finances, trade regulations, and politics of the Star Wars world. Granted this is just my opinion, but that was part of what made the prequels so lackluster. I went into this wanting a Star Wars novel, not a textbook on how to have my own Trade Federation blockade of Naboo.
They were all pretty decently done. I was able to tell the difference between the characters that he created well enough. There were some issues where he was voicing characters we'd seen on screen and thus already had a voice, but that's understandable. As a standalone it was fine.
No, I couldn't see this being made into a movie or TV series. It's a non-canon side story about characters that weren't super well developed or interesting in the first place.
If episodes 1-3 were your favorite in the Star Wars franchise then you'll likely enjoy this at least a bit. If you have 15 hours to kill or want to lull your spouse to sleep on a long drive so you have some peace, then this is the book for you. It was well written, but the subject matter was just not for me.
While interesting as a setup to the prequels there are no interesting revelations here. This book revels in the philosophical aspects of the dark side. Large Machiavellian plans are constructed, political wrangling occurring. But the characters involved uninteresting, and one note. Their interesting character traits either never fully explored, or ignored when the plot requires. And the final conflict the book spends the whole time building to.(since we are shown the aftermath first) is a non event.
