It was soo expected

i was really enjoying this move in the beginning until i found out who the bad guy was .I mean come on!!!! it was so expected it would of been better if it had some twists and turns and the bad guy wasnt who we all thought it was. this movie just kept twisting my head lol i was enjoying it until the end...those cops and detectives sucked so bad and the scripted was so poorly written . the concept was good but i felt like when they got to the ending they just got lazy and didnt care anymore
