It's remake time on the home theater front this week as 'The Karate Kid' and 'A Nightmare on Elm Street,' two classic films from 1984, come to the fore. Some people get riled up about remakes -- enough, they say -- but remakes have been around since the beginning of cinema. There were silent film remakes of silent films, 1930s remakes of 1920s silents, 1940s remakes of 1930s hits, and on and on. You get the picture. If the remake is good, we get overjoyed. If not, we curse them all. 'Karate Kid' falls into the first category: It's a pretty good take on the original that stands by itself as a success. 'Nightmare' is only passable, however; it just doesn't give us that extra jolt we got from the first one. Once past the remakes, there's something original and special: 'Splice,' a sci-fi horror film that will keep you glued to your seat. Enjoy.
