Better than the first

Plot hole number one and its a huge one. How is he able to travel back to any place in his lifetime? The first two movies had the characters only able to travel back to events in their memories.

Second. And huge spoilers ahead. How was the sister able to 'follow' him back through time. Surely each time he altered the timeline, everyone (including his sister) would experience that change but not know it.

Anyway, Butterfly Effect 3 is good. Way better than the second but not as good as the 1st.




I know one thing baby...you will survive.

1. In the first movie, he used his journals to go back to a specific date. In the second movie, he used photographs to jump back to a specific date. In the third movie, he just concentrated on a date from a police file, and went back to that date. All three movies involved the characters concentrating on a specific date to jump back into their younger bodies at that time. (This third movie just did a poor job of depicting the process, possibly assuming that it had already been explained in the previous two movies, so it didn't even bother trying to explain how the characters got into the past.)

2. Jenna was not following Sam back in time. It was the other way around. She was creating half a dozen different timelines, killing women who would take Sam away from her in alternate futures, but he didn't remember any of them after she changed the past. It was Sam who was following Jenna into the past, trying to stop the murders she had already committed.

The reason he didn't remember most of the alternate timelines was that Jenna was creating them, erasing the original timelines so that Sam would have no memory of them. Jenna was the only one who remembered all the timelines she had changed.

That's why Sam was confused, because he kept cris-crossing her between timelines, ending up in alternate timelines created by his sister, so he could not figure out why the future kept changing. Only his sister knew the true chain of events in each timeline, since Sam had no memories of all the alternate futures his sister had seen.

The movie was following Sam's point of view, spanning only a few days. But between Sam's time jumps, his sister had experienced many years in alternate timelines, and changed the past many times. The sister we see at the end of the movie was many years older than the sister we saw at the beginning, since she had erased many years of Sam's future by killing women he would have met.

When Sam went back and hid in Anita's closet, he created a new timeline where Anita got a restraining order against him, so his sister would never have a reason to kill her. But his sister would still have killed all other women Sam would ever meet, so that the same women except Anita would be dead when Sam got back to the "present."
