One of the greatest sci-fi films ever comes complete with a subtle yet poignant message. The Main Character throughline is brilliantly portrayed as we watch a sweet, yet ignorant, government employee fumble his way into meaningful growth. It's true that the throughline of the alien he makes friends with could have been developed more, and as a result their friendship, but the decision to touch on them lightly keeps this action-packed story from becoming too preachy. We can be thankful that the authors included them at all. A brilliant film that begs for an equally meaningful sequel.
