Is Hollywood losing it's charm?

Nowadays, the cinema box office is dominated by the big Hollywood blockbusters from the likes of 'Universal Studios', 'Pixar', 'MGM' or, the ever popular, 'Disney'. Although no real complaints can be made since these mainstream films have provided hours of entertainment for cinema-goers worldwide, it has to be said that as time has passed these films have become very "samey", with storylines becoming [annoyingly] predictable and a lot of films now just being adaptations or remakes. The ability to make a good sequel has never really been found, whereas the one to shock audiences has now been lost; so why are feeble attempts at both still being made?!
It's not being said that all of the products of Hollywood from recent years have been below parr, but it is being said that with some of the abysmal excuses of films, such as 'Epic Movie' or (the just as bad) 'Disaster Movie', that have been released, motion pictures are losing their charm.
Obviously, there are still the exceptions to this. Not every film is bad and some of them carry just as much charm as the black and white classics from when cinema was young and films were still a cause for excitement. 'The Curious Case of Benjamin Button', '(500) Days of Summer', 'Eternal Sunshine of the Spotless Mind' and 'No Country for Old Men' are just a handful of films from the last decade with which Hollywood have really been on to something.

They say "things get better with time", but to be completely honest, it's doubtful that Hollywood has. Where is the modern day 'Psycho', 'The Godfather' or 'Casablanca'? Maybe in ten years time people will look back and consider today's films to match up to the old classics.
Maybe the mind of a cynic with nostalgia for the Hollywood Golden Age is too harsh on modern cinema.
Who knows.
