The movie centers around an invention that allows people to view memories from any point in their life. It doesn't get bogged down in the science behind it, allowing the story to unfold. The problem is, it's not a very good story.
Although the memories of these characters are on full display, I never felt like I got to know any of them. The main character, played by Peter Dinklage, is a figurine maker, but is seemingly Sherlock Holmes as well. I don't know how much PTO comes with a job like that, but he spends all his time investigating a murder on his own volition. It never feels like he's truly given a challenge at any point, and the movie is too busy trying to throw you off the scent that it doesn't seem to care.
One thing that jumps out, however, is that the movie makes zero reference to the fact that Peter Dinklage is a little person. His stature is often the main focus of his character on Game of Thrones, but any actor could have gotten this role. Given what he lays out on screen here, the overall movie notwithstanding, it's clear why he earned the part.
Another positive performance is offered by the late Anton Yelchin. He plays a troubled young man on the brink of total mental collapse. He put all he had into his small role, showing that his untimely death robbed us of decades of potential in the world of cinema.
If you want to see a better execution of the technology featured in this movie, I would direct you to the BBC (now Netflix) anthology series, Black Mirror. Each episode is its own independent story, so you can jump in at any point. The one entitled 'The Entire History of You' delves deeper into the topic, and also happens to be my favorite of the entire series. Yes, Rememory is currently free, but you already have Netflix on every device you own. Queue it up. 5.25/10
