Too many underestimate Blu-ray

[Q?]

Sometimes I get frustrated with all the nay-sayers when it comes to the quality
of blu-ray.
when I try to explain the HD experience they look dumbfounded or
unimpressed .
I've tried to invite them to see The Dark Knight, Speed Racer
or Blade Runner.
Just to show them the quality and they just don't seem to understand
the extra dimension the HD can give you. Being a total movie geek
I'm grateful to have a decend HT setup, so I can trully watch the movies
as they where intended to be!
Have you guys been dissapointed by the lack of enthusiasm of the general
public?
And have you tried to convert the dvd-loving mortals?
