Oh for heaven's sake Joe . . .
I'm sure if they felt the need for JMS's input, they would have asked for it. Let's also not loose sight of the fact that this movie was made with people that were part of the original movie's production. I mean they already have Dan Aykroyd involved, what better consultant do they need?
Honestly, I don't know if he really meant it that way (though you'd think a veteran writer would be immune to a case of "it came out wrong"), and I'd like to give him the benefit of the doubt, but at face value this does have something of a bitter egotistical undertone to it. It's a little disappointing to see, especially in response to what seems like genuine praise.
