Strange case of Dr Jekyll and Mr Hyde

The low rating I give this book is not the author's fault. The story that Stevenson penned is a standard in 19th century science fiction and as good if not better than anything Verne or Wells wrote. At least, that's the way I probably would have felt had it not been spoiled for me. Everyone knows the relationship between Jekyll and Hyde so when the twist was revealed, it was very anticlimactic. I would love to get the perspective of somebody who didn't know the twist; sadly, it's such a part of common knowledge that I don't think I'll see that.
