The ending is laughable (the movie; I don't know about the book).
Does anyone know if Tom Cruise ever made a movie in which he did not run full out, as hard and as fast as he could? I recently rewatched Minority Report (better on second viewing) and Cruise did his running thing. Then toward the end, another character, speaking of Cruise's movie son, said: "He likes to run, like his father." I know running is Cruise's trademark, but I don't remember his earlier movies well enough to be sure he ran in all of them. What about Top Gun? I think he did run in All the Right Moves (high school football picture) but what about Legend? Risky Business, Rain Man -- did he run in those?
