In Halloween-season viewing prospects, there’s good news and less-good news. The good news is that two stellar restorations of stone-cold horror classics were released recently. They are the amazing, amusing “The Old Dark House,” a 1932 horror comedy directed by James Whale, the maestro of “Frankenstein” and “Bride of Frankenstein,” and George A. Romero’s seminal 1968 “Night of the Living Dead,” which had a long road to a beautiful new version.
