Great plot, good execution, and great performances made this a memorable masterpiece for me...

First of all, would love to see Vishnu Visal going forward selecting good stories like a proper psycho-thriller, which I haven't seen executed this well in recent years in Indian cinema. Making a 2hr 45 min long movie takes guts these days. It shows how confident the director was, with the content and as well as execution.

A lot of set-ups and pay-offs are there in the movie, which spring up every now and then making it interesting. The BG Score by Ghibran was great, kept me glued to the screen. The children performed so well in their respective roles, and so did Amala Paul, Kali Venkat, Nizhalgal Ravi, etc.. The twists were believable, and not the familiar one-twist saves all kind of mediocre stuff.

It tests your observation throwing stuff right in front of your eyes, and hiding them perfectly. Worth a watch...This is a rare kind of movie where in you get hooked to the movie right from the beginning to the end..Movies like this come once in a blue moon in Indian cinemas..Ratsasan is a gem equally as effective as that of hollywood thrillers in terms of direction and content. Last but not the least don't miss this movie, you will fall in love with South Indian movies after watching it.
