this movie doesnt need to be actually considered a sequel. if we remove the parts in movie related to ek villain 1 except smiley balloons ns mask, the whole story will remain the same. they could've just released it as a separate movie.
overall movie is not bad but not good. the main villain which is the killer doesnt show any emotions whatsoever and the only emotion he show actually is just anger where he screams. the main leads, the female lead acting is pretty good, male lead's acting is not bad but not good.
