To me it is a big let down. I just picked up my copy. It is kind of cool to hear Axl's voice again, but the songs are not GNR in my opinion. The songs are not terrible or anything and there are some really good songs on the album though.
The hit like November Rain, Welcome to the Jungle or Sweet Child of Mine is just missing. It is not a GNR album I guess.
I would give it a 5/10. I could actually give it a 6 or 7, but since we had to wait 17 years for new material from GNR and it is not a masterpiece, I can only give it 5.\
