Katrina as Maria and Vijay Sethupati as Albert are surely playing the characters well, but apart from the acting skills that they have, the film lacks in screenplay, story plot, and message. The film might look big and so on, but actually, it will fail the audience. The candles in the film Merry Christmas are Katrina and Vijay.
In Merry Christmas, Sriram Raghavan takes his own sweet time to tell the tale of a woman in an unhappy marriage and a man with a mysterious past while also making sure that his characters have abundant time to breathe, talk, and even go for a walk around town.
The stars out of 5 would be two, one for Katrina and the other for Vijay and their acting.
Do let us know how you feel about the film.
