It does suggest that the oldies were the best.
In other words maybe Hollywood just isn't making great films anymore, films that have some social impact.
I'm a big fan of Al Pacino who made some great films IMO
The Godfather 2 being one of them and a favourite of mine.
Perhaps it also says something about the critics. Those so called experts who, it would seem, have subjective view on harking back to the past.
I'm not saying Citizen Kane wasn't a great film, just that film critics are a unique bunch

Just my 2 centavos
