It's a really good show, funny at times but serious for the most part of it. After watching every eisode intensively for the last 2 months, I can say it can be boring at times.

It shows the life of a mafia family and the rise of one mafia boss, also has a lot of other good side characters that keep you interested in all events. The good side is that they were not afraid to kill the important characters during the years, it made the show seem more credible.
The ending doesn't do it justice at all though, they really should have made some sort of closure of the whole story.
A recommended watch definetly though.
