Sorry, where JP is concerned, I've read/listened to his stuff, and it does absolutely nothing for me. To say nothing of his increasingly mannerless behaviour in public and print.
I love listening to people I don't agree with, and I can give them a lot of rope *provided* they exhibit civil behaviour. Otherwise it just makes me cringe and think "you're an adult! You're supposed to be setting a model of behaviour for the rest of us! What are you doing?!"
Manners maketh the man, y'know? (Maybe this is just a deceased idea that lingers in me due to my Soviet upbringing.)
But I digress.
When it comes to films, there are two books that are really, really excellent, and serve as educational primers on the topic, and they are:
Film Art by David Bordwell and Kristin Thompson
Understanding Movies by Louis Giannetti
Further to those two, from a writing/analysis standpoint, Roger Ebert's book 'Your Movie Sucks' is a terrific read and something I'd recommend after you've read Film Art and Understanding Movies. (Ebert's masterful prose is in a class of its own.)
