The problem isn't that they try something complex, it's that they do so sometimes in outlandish ways. Rumple's character (barring season 4) was very complex amnd detailed. Then, they forgot how you had to have a reason to be turning evil or do bad things. A dream doesn't cut it for Snow, unless she had it plaguing heer her entire life, then I would understand.

Emma did pretty much no evil in season 4 and I guess they saw how terrible their attempt was an decided that making her Dark One would suffice. The problem that making the DO the cause of all things wrong is like saying Rumple had no chance at all being good if the Lightest being in all the realms fails to keep it in check.
