Ahalya - Beautiful Thriller
Initially, I was not sure as to what kind of thriller it will be - a Ghost Thriller, a Killer Thriller, Some Time/Space thriller, and then I saw it.
It is in Bengali, but the story grips you. The dialogues, acting, the direction & the editing was so powerful that it runs till end without losing the plot for once. Generally thriller/mystery films are the difficult ones, because it requires you to grip the audience till the end, and then release the bomb. This film delivers it on this parameter.
