3 out of 5 at the highest. I liked it more than most but to build on your analogy, Godfather Part III is a forgettably "okay" movie taken on it's own. As an end to the trilogy it is fairly abysmal. Some terrible choices in supporting cast and a story that never really comes together into anything half as coherent as it needs to be.

Left to his own devices, Rae's albums are always going to be spotty.
