Ok.....huiyi here...was surfing the web cos I was bored, and I found some stuff which explained why Mr Osgodby'd ask us about whether we think that Montag is a hero...
If you search for characteristics of montag this'd probably show up...
Apparently he's a 'romantic' hero...

-Birth and class are unimportant: the individual transcends society

-The battle is internal: it is a psychological war won by the “courage to be me”.

-Moral codes are eccentric–heroes make their own rules

-Passions are outside of individual control

-Self knowledge is valued more than physical strength or endurance (physical courage is de-valued)

-The hero is moody, isolated, and introspective

-Loyalty is to a particular project and to a community of like-minded others

-This romanticism is a lead in to today’s conception of the heroic which may best be characterize by the idea of the anti-hero. The world, which even in the recently passed romantic age was knowable and whose ills could be repaired by men of knowledge and courage, is no longer a familiar place. The world is hostile, unsafe, and if not deliberately cruel and unjust, is at least discovered to be without meaning, cold, uncaring, and joyless.

Yep..hope it helps in your Lit essays...
