The online edition of the newspaper «El País» publishes an interesting article entitled «El scam de la estampita en 3D». A good critical article that shows an increasingly latent reality with the "boom" of 3D movies.
And the fact is that the 3D system was not initially welcomed with enthusiasm in the United States: the producers thought that it would not be successful. However, after the blockbuster of «Avatar»Made by special cameras by James Cameron, Hollywood has only released movies in 3D but they were not recorded on this system. This is what has happened with recent releases such as "Clash of the Titans" and "Alice in Wonderland", films in which the 3D effects were added quickly and quickly in the post-production process (they are films that initially they were not intended to be done in 3D). This has meant that, especially in the first film, there are numerous errors dimensional.
In particular, movies like "Alice in Wonderland" are not worth watching in 3D as they have few impressive effects.
Indeed, this has become a business for get more money from the viewer, who has responded well to this innovative system. The problem is the price of the entrance: sometimes we are paying double the entrance of the original film for films that do not stand out in 3D format.
