Hi Jim,
This is a fantastic poem. The tone is formal. It suits the poem and subject matter very well. The poem is about a man who rubs a bottle expecting to find a genie. To his surprise, he finds a demon. I love poems which tell stories. I loved this poem and read to the last word. The rhyme is well done and consistent. It gives the poem a wonderful rhythm. The meter is consistent from line to line. The poem flows extremely well. It is a pleasure to read. You have used punctuation and grammar consistently in this poem. There is nothing to distract the reader from their reading pleasure. Great job.
