Doesn't anyone see that there's a huge dead loop in this movie?

Rating: 5/10 (25 November 2015)

First of all, it has this basic background setting: Evan can time travel with his mind, if he has something that records the time that he wants to go. So let's clear this: 1. Evan needs his diaries to go back to his childhood. 2. The reason why Evan has diaries is because he suffered from memory fragments loss and his doctor suggested him to write everything down. 3. The reason why Evan suffered from memory fragments loss is because the adult-Evan's mind travels back the child-Evan's body and took over control.
See? This is a dead loop. If he didn't have the memory loss problem, he won't be able to travel time because he had no reason to write diaries. Therefore he would never cause himself to lose memory and then nothing special would happen.
