At the heart of Guruvayoor Ambalanadayil lies an unusual relationship not explored to such extents on screen in the past: the bonding between two prospective brother-in-laws. Although all the the over-the-top portrayals gives one the feeling of something cooked up just for the purpose of the rich humour that such a pair can produce, it somehow works in the context of this movie.
The novel flavour of this bromance, to an extent, drives what is packaged as a mindless fun ride with hardly a pause in between. So, it is no wonder that when this bromance loses steam halfway through the proceedings, the film also loses its way a bit. Yet, it is pure fun as long as it lasts. For Vinu (Basil Joseph), still struggling to recover from a breakup which happened five years ago, his prospective brother-in-law Anandan (Prithviraj) becomes a brother, friend and guiding light, all rolled into one, so much so that he spends more time speaking with him over the phone than with his fiancée Anjali (Anaswara Rajan).
