This movie is a total cliche, It is a rehash of all the movies where an engaged couple spends Christmas for the first time with their families bringing both of them together. Samuel Singh is the prototype of the difficult father-in-law. His wife tries to dull the rough edges but plays it a little too close to the cultural stereotype of an Indian wife. Jake's dad is a little difficult, but compared to Samuel he is a pussycat. His mom, although a competitive Christmas decorator is the most diplomatic of the group. Given all this, the story is mostly predictable right down to the last scene.
An interesting exception culturally is that the Singh family are generational Christians even before leaving India. So the climax is especially disappointing in a face off which leave's Samuel looking anything like the best of Christianity. Fortunately, forgiveness is one of the more important aspects of Christians since they all know how much they have been forgiven.
The acting isn't bad and really neither is the story other than being so derivative. I failed to find all of the conflict funny, so I will not want to watch this again.
