I've read the Quenta Silmarillion back-to-back seven times over the years. It's not an easy work to read or understand. Took me three or four passes until I finally understood who is who, what is going on, and how the stories interconnect. But from that point on it is awesome.
But at the end of the day, it is a compilations of unfinished works. I really appreciate and admire Christopher Tolkien's work, first putting the work together in the first place and then later hammering out final versions of the key stories.
