Jules has a rather quirky yet simple plot, and it doesn't overstay its welcome in any way. The protagonist trio (played by Ben Kingsley, Harriet Harris, and Jane Curtin) share good chemistry and are fun to watch, as septuagenarians dealing with an unexpected guest. As old people, they're dealing with different kinds of things - ailments, emotional disconnect from their kids, and lacking a purpose.
The arrival of the alien proves to be a game-changer for each of them, especially Milton (Kingsley), who's suffering from increased instances of memory loss. As someone, who sits at home watching CSI re-runs all day, he suddenly feels like he has something remarkable to do. The ladies, Sandy and Joyce, enter the picture as allies, and the alien (named the titular Jules) turns out to be a friendly listener for all their troubles. They also want to help him out in his quest to repair his broken spaceship. This leads to interesting exchanges and wacky situations, all the while retaining the film's heartwarming emotional core.
The government surveillance angle was tackled poorly, and the CGI was really off in places, but the performances and the plot's irresisistible sweetness overcome most of it. The ending (and the change of mind for Milton) is somewhat sudden, and doesn't feel as impactful, but the scenes where the trio interact with the alien in the film's mid section made me smile a lot. I liked Marc Turtletaub's Puzzle with Irrfan Khan & Kelly Macdonald, and I guess I enjoyed this one a wee bit more.
