Mate, I'm not in the habit of having utterly pointless internet arguments, I think Star Wars was a fantastic leap forward for the cinema experience which is ultimately where most film makers want their movies to end up, you disagree, that's fine. I feel most would agree.
Incidentally if you google all time greatest films or 100 greatest films then there are several lists created by people other than Sun readers and Star Wars features in all of them.
Going to see A New Hope is actually my earliest childhood memory from the age of 4 so maybe I'm biased but it's a kids film, never before or since has so much effort been put into a kids movie.
I am curious though, how exactly do you think it set the Sci Fi genre back 30 years? Could you clarify that please and explain how you quantify the amount of time you suggested?
As a sidenote, just because we are kind of on the subject,
Malcolm Reynolds:
Smuggler
Kind Hearted but would rather you didn't know that.
Captain of what is effectively a "Hunk of Junk"
Has a love hate relationship with a "classy" lady on board
Want's to avoid the law at all costs
His dress sense
Sound familiar? (Not aimed at you Meridian, I know you aren't a Firefly fan particularly)
