Why am I so obsessed with Batman?

Yes, I think someone posted something about this on Arkhamcity.co.uk but I was thinking the same thing. I wasn't really that obsessed as a kid, but since Christopher Nolan's 'Batman Begins', I got really interested in the Batman Universe. First I got Arkham Asylum, then I bought The Dark Knight (The Film). Soon after that I started buying some of the comics, then the essential encyclopdia, so now I'm pretty much as hardcore a Batman fan could get... I'm really looking forward to Arkham City so much and The Dark Knight Rises! I just hope that in the decades to come, that superheroes like Batman are never forgotten, and that some stupid superhero name like 'iHero' doesn't overrule The Dark Knight...and his legacy.
