I don't understand why a movie, as the original source, often has to be "remade." I'm not talking about films being derived from another source, such as a novel. That's not a remake of the first movie based upon something like a book. That's a different "re-imaging." For example, there was the classic 1953 cinematic version of H.G. Wells' War of the Worlds. Then there was the 2005 version. It was not a remake (even though it paged homage to the first). There were three versions of Stephen King's Carrie: '76; '02' '13. Yes, some homages were paid (and, pardon for the heresy against Sissy Spacek, but '02 was the best). But they stood on their own. That's not to say a remake of original film element can't work. The '13 version of Godzilla was magnificent along with the '54 original film.
