I don't mind it THAT much, but it's a bit of a dive.

I've had similarly good experiences with, believe it or not, Newark. They've held my plane, expressed me through lanes, and also not lost luggage.
I think I've only ever been to shitty ones. JFK's alright, as far as I can remember. LaGuardia's a bit grotty, like Heathrow. Reagan in Washington is a bit of a dump as well, but I think I remember Baltimore as being alright.
Charles de Gaulle is just funny.
