My girlfriends and I went to see One for the Money. It's the movie based on the Stephanie Plum series by Janet Evanovich. I love the series and thought the movie was hilarious. I was concerned about how casting choices would play out, but I felt they did a good job.
However, I don't think the movie was great on it's own. If you have not read the books then many of the jokes and references would not be as nostalgic. I hope enough fans go to see it, so that there could be a sequel.
