Don’t come into Apollo 13 expecting a deep, acutely insightful portrait of the inner lives of astronauts Jim Lovell, Fred Haise and Jack Swigert. Tom Hanks, Bill Paxton and Kevin Bacon are basically playing stock Tom Hanks, Bill Paxton, and Kevin Bacon characters, and this is probably a good thing for a big budget summer movie like this one. Real astronauts are invariably cool, hard-to-ruffle, by-the-book kinds of people. Sometimes it seems you could set their pants on fire and it would barely raise their pulse. This makes for successful space missions but not for a particularly exciting movie.
