What is better cinema, older films or modern films?

Now, with approximately 100 years with all kinds of films, we must make a question: are the movies made in the 30’s to 60’s better than the modern films?
First of all, we can talk about the scripts. I think you can always get excellent original stories that underlie a great movie, but I think today they make more films than before, and that’s why sometimes they have to do remakes. Just as there have always been great actors, great directors have always existed; that’s why we can see classic movies like Citizen Kane, Gone with the wind or Ten Commandments and also Mexican movies from the Golden Age with the Soler brothers, Pedro Infante, María Félix and Rosita Quintana among others; or Tin-Tán and Cantinflas movies.
Maybe some people don’t like musicals, but there a classics too, movies with Fred Astaire, Frank Sinatra or Gene Kelly; musicals like The West Side Story or The Sound of Music left a mark on viewers and they can be compared with Grease or recently with Mama Mia!, but it is a not very used genre nowadays. I must say I love musicals and these three last movies are from my favorites.
The movies about wars have had great impact maybe because war is a disturbing topic on its own. Independently to special effects, the scripts have enough strength for these movies and the edge doesn’t matter, they still have been disturbing. So we can mention across the decades Gone with the wind, Casablanca, Apocalypsis now, Full metal jacket, Schindler´s list, and recently, Saving private Ryan and Inglourious basterds.
With the new special effects by computer we can see things that we could only see in our imagination, like a transformation of a man in a werewolf whit amazing realism, or intergalactic wars, but it doesn’t guarantee a good movie; I still prefer the version from 1977 King Kong, with a mechanical arm of the gorilla, over the new Peter Jackson movie 2004 King Kong with all the new technology. I think we must make special mention of the new animated movies like Shrek, Finding Nemo, Toy story, Monsters Inc., Cars or Up, from Pixar and DreamWorks, they are simply exceptional.
Summarizing, every era has its own magic, and both are good, but I thing the older movies have a little air of nostalgia, some kind of reminiscence for something we have lived when we were children or because they remind you of someone or something special, moments that we haven’t lived (like wars or the time of the Mexican Charros), but are familiar because we have seen movies, heard experiences from our relatives or simply by reading. On the other hand, we can live the new technologies to make new movies like Avatar, or the new effects by movies in third dimension (although the 60's had films in third dimension, they were not like now), that in our time will be specially remembered.That’s why I couldn’t say one of these are better; I enjoy older and new movies and for me, both have good and bad films, so my final verdict is a draw.
