All those details, measurements, and specifications! The 2nd half of the Book of Exodus is long on detail and short on drama. But, the details are actually really interesting, if you can draw back and see the whole picture.
The 2nd half of Exodus is God telling the Israelites how to properly worship, while they are still roaming in the desert. It’s important that they get the details right, since the Living God is not someone you carelessly approach. All these details are meant to help the Israelites understand who this God is who brought them out of slavery.
