funny thing:I never saw the nolan movies till a few days ago
the thing that bothers me about begins is that they make batman more about stealth,fighting,and fear [aka scarring the crap out of thugs]
I didn't get the feeling he was a genius detective:well not as much as I wanted
he dosen't even build his own stuff [batarangs he did build so I kinda forgive that]
that and I don't know who ra's al guel [sp?] was,so it wasn't as interesting
scarecrow was pretty epic though

Liam Neeson's character, supposedly, was Ra's Al Ghul; he used illusions or whatever, it was never fully explained.  I may be wrong.  Also, one problem I had with Batman Begins, is the notion of Wayne being a bad ass in jail.  I didn't get that impression he was all that tough, it was a bit flimsy.  However, it was still a good movie and made up for the previous Batman garbage films.  
 
I think they touched upon enough of the detective angle, although I understand what you're saying.  

I liked the fact that he basically uses above military grade weapons that the military didnt think was cost affective.

interesting. Well comics seem to have gotten alot better in recent time
