Some critics are getting all up in the face of this audacious dark comedy for, well, being audacious. What are we supposed think about a movie in which the characters don’t conform to Hollywood formula? The D Train stars Jack Black in a terrific, rangy performance as Dan Landsman, a loser who’s spent his life resenting not being cool. . As the self-appointed chairman of his 20th high school, reunion committee, Dan can make a name for himself. The movie pivots on that L.A. visit and what transpires between Dan and Oliver.
