Bear...
Is the greatest character in any movie ever.
I especially love the scene where Bear's rappin' with the native in the swamp when a 6 foot monster dildo spews acid all over the natives face (eh? eh?) and Bear shoots mindlessly at a bush. Then the characters elsewhere, hearing the screams and gunfire, simply remind themselves: "Don't worry about Bear."
And who can forget such classic lines as "Yes sir." "Damn." and "Hoorah!"? I sure can't.
Movies on IMDB are not overrated, you're just of the minority that doesn't bloody LIKE THEM!
