Just watched the film, and I have to say its a pretty good watch.

The plot might be a little basic at points, but it has a very strong vibe about what it is that makes a person. Are we simply the sum of our memories, or is it how these memories shape our responses that decides that? What kind of memories are more valuable than others, is it the good ones or the bad?

That is what one character pretty much has to decide on a regular basis or die, but its what he decides to do in the end to sacrifice his memories to protect the very person that made those memories so special to him... it simply made the fight at the end of the movie (its a film about robots, there's usually a fight scene at the end of it for one reason or another) that makes it all the more epic.

Animation wise; bleh. Story wise; a good watch. Moral wise; we are more than our memories, don't let the bad ones stop you from making good ones.

Also, main character's voiced by Charlyne Yi who voices Ruby in Steven Universe, so there's that too.
