I really enjoyed the movie, it reminded me of the games, and I really love the modern take on Nancy. The acting I quite enjoyed and the plot was very much like the books.
There were a few scenes in the beginning that were supposed to be funny but weren't that funny to me, but as the movie went on (like past the 10 minute mark), it got better.
This movie was very fun to watch, I believe kids and Nancy Drew fans alike would really enjoy themselves during this film. BUT, you have to remember that this is a MODERN take on Nancy Drew and is only rated PG.
