Oh boy...
Keep in mind that out of the hundreds of studio films coming out of Hollywood every year, only a very small handful can be considered effects heavy.
There's plenty of great stuff out there; it's just that the tentpoles get all the attention. Fact of the matter is that smart, challenging, sophisticated films usually don't make any money-this is as true now as it was 40 years ago.
If you're not happy with the movie industry as a whole, and you're looking for somebody to blame; then smack the nearest Twilight fan in the face. That one franchise will do more damage to the quality of films than CGI ever will. And don't even get me started on the goddamn remakes...
