Hard disagree. The book is way better. Don't get me wrong. The movie is good but it's basically a satire of fascism that backfires spectacularly (which is why it's so good). The book on the other hand is just a straight love letter to right wing authoritarianism. The mobile infantry are also much cooler in the book. I much prefer the idea of the 'cap trooper' where each individual trooper is in power armor and gets shot out of the capital ship like a bullet. In the book like 3 troopers are enough to destroy a whole city. Also the movie cuts out the other aliens, the skinnies, and that opening chapter where the infantry just fucking wreck them is great.
