America , in other words , is headed straight down the historical toilet , along with Nero and his fiddle ( or rather Dick Cheney , who 's anointed with a throwaway reference to the " emperor " ) , a thesis that Mr. Moore continues to advance if not refine with another hour and a half or so of alternatingly entertaining and distracting found footage ; some stirring archival images of Franklin Delano Roosevelt ; snippets from charming home movies ; and assorted weeping , gloating , pontificating and sensible talking heads .
