If the opening of “Clerks III” this week has you feeling nostalgic about the earlier films of writer/director Kevin Smith, you’ll hit a dead-end when searching for one of his greatest accomplishments – 1999’s religious satire “Dogma.”“Dogma,” which stars Ben Affleck, Matt Damon, Alan Rickman and Chris Rock, is currently not available to stream anywhere or buy digitally, and the out-of-print Blu-ray frequently sells for around $100 on the secondary market. While religious groups were bent out of shape by the movie, it was warmly received by critics (Roger Ebert gave it three-and-a-half out of four stars) and made $44 million at the box office (it only cost $10 million).
