Yikes! I thought I'd already posted my feedback here, but I must have just been dreaming about it.
So let me reiterate that I really like this story. It's inventive, it's long and involved and complex without ever being boring or confusing (at least to me), it takes its main characters through some amazing situations - often self-inflicted ones - and shows them growing as they age and learn to love each other. The character development never feels forced or unrealistic, and for the most part Lois comes across as the more level-headed and mature of the pair (her refusal to give Joe any encouragement, her faithfulness to her marriage and to her children). And Clark's initial idiocy and teenage lust fantasies eventually fade into the ether and allow him to fully commit to Lois because he loves her and his sons.
That doesn't mean that there won't be any speed bumps for these two. Nor does it mean that Unanswered Prayers will be all bliss and afternoon tea. Besides, we still have Billy and Serena to deal with, not to mention the aforementioned Mindy and her evil machinations. And Sam is now open for an honest romantic attachment. And we've yet to meet the highly-praised Ashley, Van-El's lady. As Natascha suggested, this could be the jumping-off point for a number of stories, not just UP. So maybe you could suggest some story lines to your muse and see which ones look promising. And maybe we'll enjoy more tales of these two enterprising young newlyweds.
After all, they still have that big wedding to plan, don't they?
