What I thought of it: Honestly, this is what I thought Byron's poetry would be like: romantic quests, flowers, love notes, occasional tales from the land of Gondal, which the Brontës made up to amuse themselves before they all died of tuberculosis. I'm sure at the time it was very meaningful, and it's made even more meaningful by the fact that the author died unmarried and childless at age 25. Unfortunately, it isn't my kind of poetry. My kind of poetry turns out to be what Byron really wrote.
But should you read it? If you like romantic poetry that's more about imagery than adventure, this is the poetry for you. Most of it isn't very difficult to understand or relate to. Just make sure you get a version that just presents the poems and doesn't try to analyse every slip of Emily Brontë's pen, unless you're a Brontë scholar.
