Honestly I didn’t like the movie at all. It was confusing and just bad overall. Firstly, the visions he was having were confusing. I couldn’t tell which visions were imaginations or memories. Secondly we focused on the main character the entire time. I think it would’ve been better if there were scenes where someone realized something wasn’t right and set out to find him. Thirdly, this movie has no explanation at all. Who was the blonde girl he kept seeing and she said “I love you,” in the visions? Who was the little kid? Was that little him encouraging him to continue? Lastly, the story wasn’t dramatic enough. I understand it’s based on an actual story but for dramatics the flood scene could’ve been real instead of a vision! That would keep the audience more on their toes. Instead, the situation remained the same, trapped by a boulder. Nothing more nothing less
