I found this to be a very pleasant movie, full of wit, romance, comedy and a bit of eccentricity as well. Tom Hanks is a Master Actor who gives us, once again, an excellent performance. His gestures, movements and the imitations to segments from his previous film, show us just how much he is capable of delivering in his job. His chemistry with Meg Ryan is absolutely fantastic, you can see they really enjoy working together and this is, no doubt, what makes over 80% of the movie succesful.
I dont think Meg Ryan is a great actress per se, but she shines in this kind of movie, she really does. The movie takes place in none other than art mecca New York City, Hanks playing the part of a bookstore magnate, just opening a huge bookstore on the Upper West Side, leaving small bookstore owners like Ryan (who owns a charming childrens bookstore just around the corner) very much out of business.
Theres a parallel in their personal lives as well: a relationship through e-mail that dont know about... just yet. The comedy keeps developing, supported by great actors like Greg Kinnear, Jean Stapleton and Parker Posey.
