This might be one of the worst movies I've seen in a while. As a person who has a passion for physics and actually got a degree in it, this is a huge backhand slap to the face. It felt like the writer, even though this script felt like it was written by AI, had a drama in mind and just so happened to be watching groundhogs day and decided to just mash the two horribly together. So many things just didn't make any sense or had no purpose other than "hey hey, remember this is a physics scifi drama" The only thing that was keeping me entertained was the physics assistant that helps our main character, even though the movie never really gave her a resolution and just had her fade into the background. Finally, the ending, YIKES. So she accepts that she's an entitled cheater and then goes back and gives herself the pills. But, it doesn't explain who made the pills or how she figured out how to control them and go back to that exact time, or was she like a ghost or something since the younger version couldn't see her??? So many unanswered questions!!! Good Lord, I need to take one of those pills to go back in time and forget I watched this movie.
