I started watching this movie with high expectations and i did like the concept, however, it soon started to go off track and had no logic left. If the spider gives power of vision, why did tahat had wrong vision about the three girls killing him? Also cassie came to know that the three girls do posses powers which will show it's effect later, but how did the three girls get power, what is their background story?was never shown. How did they coincidentally meet at one place? Also for a person who is accused of kidnapping three girls, killing police officials in metro station, stealing a cab(probably), Cassie roamed around the city quite freely and also travelled to Peru passing all the airport checks which was a glaring plothole. Also during the fight scenes in the last the villain becomes incredibly slow in action, but he is otherwise very fast to track down the girls when he is told about their location. I found many things very absurd and many loose ends were left, may be they will be covered in a sequel, I am not sure? But still the movie had too many plot holes to ignore.
