Yeah, you don't have to read The Silmarillion too intently. Its biggest value is for historical background to LotR. Feel free to skip what you think is boring. If you have the book, you can always go back to the boring parts.
TBH, if you get books like The Children of Húrin, Beren and Lúthien, & The Fall of Gondolin (also possibly The Fall of Númenor), you can skip big chunks.
