As far as sequels go this isn't awful. A lot of money went into this and the acting is excellent by everyone.

The sparkle and grit and realism that appears in almost every frame of The Godfather just isn't here. Some of this seemed forced and contrived and overall the story is quite grim and depressing. Even in The Godfather there were a few scenes here and there that were light and slightly amusing. You get none of that here. Everything here is black.

I also think that this a little bit too long. I think it could have moved faster.

All in all it isn't something I would watch a second time. Not like the original, which is a product of it's time.
