It's my son's favorite book. We read it every night (since I got it for him) before bedtime. I gave it 4 stars instead of 5 because I agree with one of the reviews that the book has so much negativity specially the illustrations. My son noticed that and kept saying the word "angry" while flipping pages until he reached the last 2 pages and then said "happy". The anger is strong in the illustration; I wished it had less angry vehicles. The story itself is not bad but the illustration makes it more negative.
