Filmmaker Joe Nicolosi had his mother watch Inception, then sat her down and asked her to retell what she had just watched, and finally, he animated her version of the story. Explaining Inception would be quite a task for anyone, but this mom tries her best (and succeeds in heart-winning where she does not in plot points).
A spoiler about Mom-ception: she confuses Matt Damon for Leonardo DiCaprio, which is just perfect. I cannot wait to grow up and confuse the crap out of Miles Ansel Tel-gort and the dude who was in The Fault in Our Stars.
