Just Didn't Work
I went into this with high hopes because it looked interesting, but it was just too long, not scary, and too repetitive. It started out good with the time loop twist and then some religious undertones, but then it just became the same thing over and over. The characters running away, screaming, running away, and then screaming more. It just became way too repetitive and I was so tired of every character screaming their head off, especially Becky, that I was hoping that they would stay dead. Too bad Travis didn't touch the rock the first time and then he could have just got everyone out then since he was willing to sacrifice himself already at that point.
One question I do have is that, would Travis still be alive at the end? When Tobin exits, he is brought back to the beginning of the film. In that certain point in time outside of the grass, Travis was still alive somewhere else in the world, but the film makes it out the he dies in the grass. Also, what happened to the mother? Was she not good enough to be saved? It seemed like she refused to give in to temptation and and thus was killed for refusing it and trying to save her son, but she didn't get redemption or to survive at the end?
