As for this Purvis Wade hate i don't get it. I really don't.
It's really really simple, some people, who are very passionate Bond fans, think the films they wrote suck. That's it, that is all there is to take on board.
The producers themselves decided CR and QoS needed heavy revising by a much more expensive writer (Haggis) - I didn't choose that, the people making the film did, and that says something alone.
But the fact remains, nobody hates them, some people just think they should be replaced. Personally I strongly think that a single, quality screenwriter would be much better than getting various extra people (ontop of two!) to constantly revise and change their work to make it better. With all the script manipulation from various members of the Bond production team ontop of that it's a wonder we get anything at all coherent.
Honestly i think them and Morgan are gonna come up with a great script.
It's nice to see the optimism, but personally I think we'll get the same as before:
P&W will write some trash that Morgan will heavily revise over to try and improve, which he probably will, but it still can never be as good as a single, quality writer's vision pitched to the producers and overseen in it's mutations with that single vision in mind. The more writers you put into anything, the more it will lose coherence, the more you will get dialogues and character directions which don't seem to hold the same consistent tone or arc and the more you lose that all important single 'vision' which great works all come from in any art form.
This is the basis behind the saying too many cooks spoil the broth, and with writing in particular it is very true. I still lament the unreached potential of the Casino Royale film, despite how cool it was at first.
