One word.. Finest till date.. These webseries is one of the best that came out of india..
Its gripping and everything else is top notch too - acting, screenplay, writing, casting and the best part is story telling.. Yes it has some nudity, some f and c words, some horrid scenes.. however compared to other webseries the content of Paatal Lok outweighs all negative things about this show.
Do yourself a favor.. Go watch it. This will never disappoint you even once.
