I watched Minnaminungu (Primevideo w. Eng. s/t) as I was swayed by all the rave reviews!
To sum up, this is a sad, sad, SOB story. Its okay but not a brilliant film.
As with a significant number of Malayalam films, the characters were real, the sets, the location, etc. were very real. The camerawork was good. The acting for the most part was effective. I wasn't impressed by Charu the daughter (Rebecca Santhosh), she came across more as fake rather than callously indifferent to her mother and grandfather's situation which is what she really was.
Surabhi Lakshmi as the mother was for the most part quite real but it stretched the imagination that she would go to such an extent as to sell her house for her daughters future. She also did not act these scenes convincingly. Likewise her father (Balu Narayanan) was good until the house selling part when he too was not convincing.
The plot is fairly good though as I mentioned above, it has not been enacted convincingly towards the latter part. Also the movie dragged quite a bit.
Minnaminungu is watchable for sure, but its too much of a sobby story, mediocre towards the end.
Just goes to show that everyone has a different perspective and one can not blindly go by other peoples reviews.
