Not the best, not the worst.
Some of the comedy was really forced, and I could tell that the actresses didn't find the guys 'being funny' terribly funny. On the other hand, this movie featured a performance by the mighty Eli Wallach, and even provided a kind of tribute to him in the form of the tribute to the fictitious character he was playing. The man is gold.
I didn't think any of the characters was as charming as they were meant to be, but it was a passable romance largely because it was split into two mini-stories. The one thing I thought was really cheap was the 'I can't cry' thing because it was so obvious that it was going to pay off in the third act.
All in all, not a wildly entertaining film, but not boring, and it at the very least acknowledges its debt to a rich history of great films.
