Though the movie has a lot of similarities to the Hollywood movie HALLOWEEN , this movie should be appreciated by for it's making and the work put in . This one is the best of it's kind in recent years . With amazing cast performances and awesome story telling Raatchasan keeps you in the edge of the seat . Though I was spoiler about the movie through social media , this movie just made me get excited and still surprised with every twist and turn . This movie might just make all the way to all time best psychothrillers in kollywood .
