I'm in the minority here, because I actually _liked_ this episode!
Especially after my complaint about the way the show handled Lois's amnesia, and of course the early episodes where Lois couldn't see what was standing right in front of her face, I loved seeing a Lois who would know Clark anywhere, in any body. (I also enjoyed the humor in the episode, but that's neither here nor there.) The point is, you did a great job with this!
I think you achieved your objective; you tied everything together and showed the unification of the two sides of Clark into one person. And, yes, showed that after all they went through, there was a happy ending. It was a nice finish to your 4-part story.
