Why is everyone mad?

Everyone seems so upset with this game, but so far I havent had any problems. Its great watching the world go by, and its really fun in the car. Of course, I only have two train cars, 6 animals(two in storage), and less than 1,000 coins. After reading the reviews, I dont completely trust this game. If I have any problems, you WILL hear about them.
