The story is basically planning a wedding for Christmas on short notice and things like work get in the way.
The acting seems just like acting, not smooth and natural. Just a tiny bit off.
I am not a fan of wedding planning movies. I suppose if you like them, this movie is OK. But the story is fairly mundane and the dialogue is flat.
The only romance is the two getting married, so there is no relationship development. In fact, like many wedding planning movies, there is relationship devolvement for a while. Everything starts out roses but the couple encounters situations that lead to resentment. As expected, they both start to question the wedding.
Pretty much all the supporting characters are upbeat even in difficult situations. The head boss, instead of being scroogy, is accepting and encouraging even with a looming deadline and then later after a failed presentation. He is demanding but doesn't criticize. These movies always struggle with realism, but the people are a little too Polyanna.
There is a bit of real wisdom during a conversation between the guys while driving late in the movie. People expect perfection on wedding day maybe a little too much.
This movie is family friendly although it probably won't appeal much to children.
