I thought that these were funny and the more you think about them the more you wonder WTF? John Scalzi (author of Old Mans War) brings up some excellent points-

In Star Trek: The Motion Picture, a Voyager space probe gets sucked into a black hole and survives (GAAAAH), and is discovered by denizens of a machine planet who think the logical thing to do is to take a bus-size machine with the processing power of a couple of Speak and Spells and upgrade it to a spaceship the size of small moon, wrap that in an energy field the size of a solar system, and then send it merrily on its way. This is like you assisting a brain-damaged raccoon trapped on a suburban traffic island by giving him Ecuador.”- John Scalzi
