18 December 2014 | by (Bradenton, Florida) – See all my reviews

"Rivals" is an okay episode of "Star Trek: Deep Space 9" and nothing more. It begins with a conman, Martus (Chris Sarandon) getting arrested by Constable Odo. While incarcerated for fraud, he meets an odd alien with a hand-held gaming device. The guy unexpectedly dies and Martus uses it to construct larger gaming devices--and he opens a bar across from Quark's. Soon Martus seems to have the midas touch.

At the same time, Dr. Bashir and Chief O'Brien begin playing some futuristic version of racquetball. O'Brien is totally outclassed and playing him isn't fun because O'Brien is so hyper-competitive. So how does this plot intersect with the plot involving Martus? And, more importantly, does anyone really care? I sure know I didn't particularly care for this one. Very skippable.
