There are obvious advantages to being a grumpy old man.
Disregard for societal norms, the ability to say “Back in my day…” and of course, senior citizen discounts.
Battle of the Worlds is basically Claude Rains trying to trying to tell the leaders of the world that a massive meteor is heading to earth and will probably kill us all!
They ignore him because he IS a grumpy old man.
End it all now, Giant Meteor!
