What about a conspiracy to murder that instead causes brain damage and a week long coma that results in amnesia and a ton of bruises? There are plenty of ways you can make amnesia interesting, it's just reliant on your creativity and skill as a writer. I'd say that you've been Rping with people using amnesia as a crutch rather than a legitimate writing tool. Im sorry for that.

EDIT: Didnt adress the part where my example resembles a soap because there was the inclusion of a coma BUT THEY EXIST IN REAL LIFE JUST LIKE UNICORNS!!!
