“Grizzly Night” (*1/2 out of four) was a grizzly bore about a ferocious grizzly bear on the loose and various townsfolk (Charles Esten, Oded Fehr, Brec Bassinger, and others) who have to steer clear of its path. They should have steered clear of the movie instead. Plodding and lumbering, like the bear itself, and even the attack scenes are pretty tame and turgid. Yet another movie seemingly inspired by the success of “Cocaine Bear” but the movie it actually rips off the most is “Silver Bullet.”
