when the 1st one came out, everyone was stunned and the low-budge film attracted umbelieveably high interest and profit, and i think not many anticipated that it's already the 4th one that came out last year and still counting.
Now i wonder how many episodes will it take to explain things thoroughly and put a satisfying ending to the story- though i don't want it to ever end, as it is one of the most remarkable and thought provoking horror films of all time.
