This is an interesting experiment in retelling in a specific poetic form. So precise and slim is the style that I cannot imagine understanding it without contextual background (mainly the Volsunga Saga) to fill in the gaps.
While the effort is admirable, I didn't find it added anything fresh to the original works. It wasn't very entertaining either. But I'd recommend it to those interested in the Norse myths and sagas and Tolkien's exploration of them.
