I've never liked the idea of soul mates, either. The whole concept grates on me. Then, on top of that, we have to accept reincarnation.

Then there's the curse. I suppose I should be able to accept the curse idea, but I question H.G. Wells timing. Waiting until after their third attempt at getting married finally succeeded? Why didn't he show up as soon as they were engaged? Or at any other time prior to their marriage?
Agreed.
One fanfic (name can be found on request) had an interesting take. The author had Lois and Clark sharing the info on the curse with Alt-Clark and Alt-Lois, who immediately shacked up. No marriage, no curse. (Not sure what happens when they become married under common-law, though.)
