"Poltergeist": The 1982 haunted-house classic by Steven Spielberg and Tobe Hooper gets a CGI-laden remake. Sam Rockwell and Rosemarie DeWitt are the terrified parents whose daughter disappears into the family TV. The movie was not screened in advance for critics, so go ahead: Be afraid. Rated PG-13: for intense frightening sequences, brief suggestive material, and some language.
