Another re-make of a re-make of another film remake

Just reading a piece about the release of the latest re-make of"The Great Gatsby." For whatever reason - lack of original ideas springs to mind - they're re-interpreting it again for this generation. Personally, a large proporation of the film remakes that I've seen rarely matched up to the original. This leads one - me - to wonder why producers/directors/film production companies feel the necessity to update a film that on the whole, was good.

In the way of background information and according to Wikipedia, the story, "narrated by Nicholas "Nick" Carraway, a 30 year old Yale graduate and WWI veteran from the midwest, who takes a job in New York as a bond salesman. He rents a small house on Long Island, in the (fictional) village of West Egg, next door to the lavish mansion of Jay Gatsby, a mysterious millionaiare who holds extravagant parties."

Checking further with IMDB, the first film version dates back to 1926 and starred Warner Baxter as Jay Gatsby and Lois Wilson as Daisy Buchanan. Furthermore, much to my surprise, a stage production opened at the Ambassdor Theater on February 26, 1926, ran for 112 performances and was directed by George Cukor.

The next film version in black and white, was made in 1949 starring Alan Ladd and Betty Fields. I always liked Ladd as an actor and although I never saw the film, most likely he did a decent job. The next incarnation in 1974 was the one that I watched and being an admirer/fan of Robert Redford, I thought it was...okay mainly because he was in it. Didn't particularly care for Mia Farrow as Daisy and thinking back, there was very little chemistry between the two stars.

Last but not least, it appears there was yet another version in 2000 (wasn't aware of this) with Mina Sorvino and one Toby Stephens in the lead roles.

That brings us up to the latest incarnation to be released in May 2013, starring Leonardo di Caprio and Carrie Mulligan. Somehow, di Caprio, at least in my mind, doesn't have that suave, sophisticated personna necessary to play Gatsby. Then again, who knows.

This is all leading up to the question originally posted here, as to the necessity of yet another re-make of the re-make of.... One re-make is acceptable or even two re-makes but five? The point being made is that script writers should be searching and coming up with their own ideas, rather than turning out scripts based on the story lines and scripts created by other script writers.

In as far as the newest and hopefully the last version of this story, I'm going to pass but for people who are intrigued to know what the film is about, here is the trailer: http://www.imdb.com/title/tt1343092/?ref_=sr_1
