The Silmarillion is just a collection of short stories and scribblings. It doesn't have an overal narrative focus. Reading the Silmarilion cover to cover is like reading the Bible cover to cover you won't enjoy it.

CT did a good job with Children of Hurin. The more developed stories (Children of Hurin, Beren and Luthien, and The Fall of Grondlin) were going to be stand alone novels with several drafts finished before JRR's death.

Having read the Silmarillion you should recognize these stores spanned several chapters and had a clear narrative focus unlike the rest of the slog.
