Cobra is a sleek, extremely violent and exciting police thriller.

Whereas Clint Eastwood simply would have squinted at Robinson, Stallone takes a more violent approach. Maybe that's the difference between actors--Eastwood can be droll; Stallone more often crosses the border to primeval.

A disturbing movie from many points of view: disturbing for the violence it portrays, the ideas it represents and the large number of people who will undoubtedly go to see it and cheer on its dangerous hero.

There is not nearly enough violence. No one is eviscerated. The villains, all mumblers to a man, are not punished by having their tongues cut out. The body count is only somewhere in the high eighties - and most of these are simply gunned down with a deplorable lack of invention. Very little is done by way of eye-gouging, limb-crushing or tooth-extraction.

It's fast-paced and full of gaudy action, yet it's thoroughly unsatisfying, largely because it's so lazy: once Stallone (also the screenwriter) and director George Pan Cosmatos have sketched out the standard genre archetypes, they leave it at that, not bothering to fill in the niceties of characterization, plausibility, motivation, and suspense.
