You'd have to define "good". Bulgaria is beautiful and has great nature, historical sights and amazing folklore tradition, the local cuisine is really good and people are welcoming - in that sense it is a really good place to visit as a tourist. On the other hand, there are certain problems it's facing in the economical field, being the poorest EU member and, in my personal opinion, isn't governed well.
No, Bulgaria is not the worst country in the world. Like any country, there are good things and bad things about it. Bulgaria has many positive qualities.
In general the Eastern European countries such as Bulgaria and Romania are worst, especially for air pollution.
