This is again one of those films that thrive on the talent of the writer, but not essentially on the ability of the writer to spin a story. The key here is quirky characters and quirky dialogue.
You can guess all the plot turns miles ahead. But at some point, this familiarity and predictability becomes a strength because it makes all the situations credible. When you go for all those fancy twists, some times the universe of the story gets pushed into another realm which is not relatable any more. This film demonstrates that, if you choose your subject appropriately and can write great scenes, you can get away with being predictable.
And don’t misunderstand me. Vicky donor is not a great film. But it does have some interesting characters and entertaining conversations. You won’t squirm in your seat for the ordeal to end.
