This was pretty good cause it showed you what could happen if you alter things and expect other versions of you to just understand. Think of the different wavelengths humans are on in your own universe. That is how you should see this kind of situation. Annie was really a clueless chafector. I wished the movie went a different direction cause i have a lot of questions. I really did enjoy the idea of the camera and frequencies. I dont understand how those letters or the camera got where they did. The movie lost me at that point but overall it was a good idea and annie irritated me a lot. Some ppl just dont know when to stop.
