Few things are as annoying as a really good film that falls apart at the very end.
Men are cattle.
Exactly why this is, they don't say, nor is it all that necessary. What we've got is sitcom, and what makes a good sitcom work is a combination of good writing and performances. The banter created by writer Elizabeth Chandler sparkles and Jackman, Judd and Tomei have great chemistry together. The occasional use of cinematic asides doesn't always work in a movie, but it works here although there isn't enough of it. As was said before, until the last five minutes, this is an almost flawless romantic comedy.
