You’ve gotta read it. I’d say it’s pretty widely regarded as the best SW novelization. Definitely better than the movie.
Very minor spoilers, but it happens in the movie too so it’s not really a spoiler.
The only thing I didn’t like was when Anakin was slaughtering the separatists, he had some really cheesy lines. They did serve the purpose to show that he was enjoying the power the dark side brought him, so I guess there was a point to them, but it felt like Stover was having a bit too much fun with it.
Other than that, amazing book, I would definitely recommend it.
