I'm actually very disappointed by this. In almost any case, I prefer a 5-star system over a binary thumbs up/down. A more detailed rating system allows me to differentiate my absolute favorites from content I thought was merely interesting. It also helps me to do pairwise comparisons of different titles. If my only option for saying I like something is "thumbs up", then I lose a significant amount of information about which titles I like more.
