There are many flaws in this film... like how did vikram get to know that shekhar 7.30 ko aya hoga ghr ... like shekhar would have come before him at home when it wasn't raining and how did he get to know that watchman wouldn't have seen him leave ... which gave him idea to change the shoes .... there is no explanation... Also that why didn't police check Shekhar's phone as he was murdered... if they would have checked shekhar's phone then they wld have found the message from him to vikram's girlfriend abt law case suit and would have found the motive for vikram to kill shekhar..... there are no explanations ... also why didnt police ask watchman if he saw any torch lights from any house that sonakshi did... thriller film shld have these many flaws ryt when there are so many twists
