How bad is it? Bad enough to end Jay Leno's brief movie career.
Should you see it? Sure.
This is a fish-out-of-water buddy-cop movie, starring Pat Norita and Jay Leno, with Ernie Hudson, Tom Noonan and Randall "Tex" Cobb. It's not the 1967 Chinese UFO film of the same name (aka Bamboo Saucer, which is worth catching) or the 2012 film that I've yet to see. There's an experimental turbocharger for autos being smuggled from Japan and Tokyo's Norita gets teamed with Detroit's Leno, though they are always at odds. Leno's jokes are not only racist, but sexist - yet he's like catnip to the ladies! There's a decent shoot-out on a train where the bad guy explodes, a chase scene with a fruit cart (is this the 1920's?) and John Hancock as the screaming black chief of police. Leno apparently forgets he's been shot in the leg and Norita jumps through a windshield, decapitating a driver with his kick! It looks like they ran out of money for editing and post-production, so it's rough and clunky. If Samurai Cop didn't exist, this would be the silliest cop movie I've seen.
