It's a romantic comedy with Ben Stiller and Jennifer Aniston in the main roles.
The plot is very funny and even not being totally innovative it has some different characteristics from some other romantic comedies. I enjoyed the ending of this movie, something that I usually don't in romantic comedies, and that was because of even being predictable the ending was funny!
The Anniston's character is just great. She's funny, nonsensical, but at the same time very independent and sweet. The character played by Stiller is the typical guy who wants a compromise, to be married and have kids; but he will change with her. To the point that near the end he just says: "I don't want to get married. I just want to take you to dinner, sometime this week".
I liked the plot, the jokes, the characters, and found it a very entertaining and some kind of different romantic comedy!
