I guess we'll have to agree to disagree, DSDragon. No amount of confusion on Lois' part would make me buy the ending. Sorry.
I guess I'm also kind of pissed that there were so many questions raised and left unanswered. I hate not knowing what's going on. And I don't care if there's a sequel, because the way they handled it definitely lessened my enjoyment of the movie. No sequel will be able to fix that.
Just as an aside, I never particularly cared for the Jason plotline anyway. I don't want to see L&C as parents. That's just not something I find interesting.
