Just a few more minor thoughts on Catcher...
Although HC's 'fight against the world' likely reads best at a certain point in the readers life, the book still can work later when said reader is likely more critical of HC's POV, no? I'm not sure we're to read his telling of his recent past from a mental hospital bed as entirely pro-HC. Then again.
And even if we are, look where Salinger heads next - Franny & Zooey. If Catcher is read as the big bad world teardown (or connected personal break up), F&Z is the resulting personal build up (and a much better book - or two connected shorts). Probably the reason Catcher is found in so many murders pockets and F&Z is not. Course by F&Z we're introduced to the Glass family and the world gets a whole lot more complex (and Salinger begins his slide to checking out, drinking urine and watching non-stop Andy Griffith Shows).
Also, as Jacob hinted at above, how you approach Catcher fresh when it's become so culturally saturated? Everyone's already seen HC's POV repeatedly if they've several dozen movies, hundreds of pop songs (even genres?), who knows how many novels/shorts, etc. Does it read like it should be banned now? Did its success make it irrelevant?
Unfortunately, someone else fucking liked the name too.
The real deal.
