I'm unable to comment on this (well-written) article in any meaningful way, as I've never watched Sex and the City, or seen either of the films. But whenever people use that horrendously overused word "toxic" in these sorts of contexts, the contrarian part of me wants to like such entertainment on principle, just to piss them off.
On another note, my wife has warned me I'd hate the series, and I'm sure she's right, but I must confess I was tempted to see the second film, purely because of this legendary rant from film critic Mark Kermode (who I actually knew for a time, whilst I was at university). It is absolutely hilarious. You should definitely take a look. :)
