I prefer the Goodreads rating system which compresses 1 and 2:
1 - Did not like it
2 - It was ok
3 - Liked it
4 - Really liked it
5 - It was amazing
The reason being is that most books won't end up being 1 or 2, and there really isn't much difference between them. But it sucks giving 2 stars to something that wasn't bad. Perhaps emoji arranged in a non-star-like pattern would be the best.
