The movie was witty and funny and they made a great pair - good chemistry together, however, it ended strangely. It almost felt like they cut it (edited) or cut some scenes that helped explain why their relationship (marriage) ended in the first place. I'm a sucker for a happy ending, but even still, an ending that was more evolved would have been better and would've let you leave the theatre more satisfied. To be closer to reality, you would like to understand, even with humor, why it ended the way it did.
Jennifer Aniston is in so many movies these days that her characters all run together and become unbelievable after awhile. She is over-exposed. Aaron Eckhart was excellent, but anyone could have played the female lead. The movie was ok, but I wish I waited to watch it on regular TV. You never bought in that they fell "in love".
