Nonetheless, "On_Line"--taglined "reality is the ultimate fantasy"--at times comes across as cinematic onanism, not only in the physical-act sense (which rears repeatedly) but also in its almost preening attentions to personal minutiae; the characters are so self-involved at such a deep level that they remain in their own worlds, shut off to that extent from moviegoers. Occasionally, they just seem silly, agonizing over the unimportant. However, any film with Hamilton is worth a watch, just for that. Starring Josh Hamilton, Harold Perrineau and Isabel Gillies. Directed by Jed Weintrob. Written by Andrew Osborne and Jed Weintrob. Produced by Tanya Selvaratnam and Adam Brightman. An Indican release. Drama. Not yet rated. Running time: 86 min.
