Aide from the so-ridiculous-you-can’t-even-consider-it-sacrilegious musical show-stopper “Rock Me Sexy Jesus,” star Steve Coogan is the only thing Andrew Fleming and Pam Brady’s parody of inspirational teacher movies really has going for it. As Dana Marschz, an endearingly inept former actor who traded in a mediocre career of appearing in infomercials and STD ads for a gig teaching high school drama in Tucscon, Arizona, Coogan invests the character with such wonderfully hammy bravado that you can’t help but admire his misguided passion.
