You hear a lot of complaining, and rightly so, about Hollywood's tendency to churn out safe, unimaginative pabulum--the remakes, the sequels, the blow-everything-up movies. Less remarked upon is the opposite problem: The studios' inability (or unwillingness) to make B+ movies, competent, mid-sized genre films that are formulaic in the good sense. There was a time when Hollywood excelled at producing such solid but unexceptional fare--Westerns are the classic example--but no longer.
