Nora Ephron did When Harry Met Sally and You've Got Mail, as well. I really like her work, when I know it's her. I didn't actually know it was her on this one, but now that you mention it, I can see it.
I just saw it this afternoon and thought it was pretty cute. I liked that they didn't just do the same characters in a movie, but instead built it around the redoing the show. I didn't really like how they did the typical Hollywood one-date-now-you're-mine romance, yet at the same time it worked for the story.
They did leave a couple things hanging for me at the end--some side characters that I would liked to have seen a little more resolution for, especially for her dad. I guess it was pretty much resolved, but I would have liked a little more at the very end.
Was there anything after the credits? I didn't stay for them, so I could have missed something. I always feel like I should stay just in case, but at the same time feel jipped if I stay and there aren't any extras.
