I wonder how George Martin was viewed after he was brought in as the first composer to follow Barry. And then Marvin Hamlish. Hell, I don´t think Michael Kamen was getting a lot of applause for his work. And we all know what happened to Eric Serra.
The point I´m trying to make is this: John Barry defined the Bond sound. Not for one actor-era - but as a constant for the first four actors.
Everyone who has to follow that kind of dominance will be criticized for:
a) being not like Barry
being too much like Barry
c) bringing nothing new to the table
Nobody really can succeed at this job after Barry, I´m afraid. Because the James Bond sound is so distinctive that you just have to emulate it. It is such an integral element to these films that you cannot change it (too much). In the end, it all sounds like Barry because it has to.
So maybe the only alternative is: getting a new composer for every film, so we get used to people doing their version of a Barry-Bond score. But nothing else.
Changing things up with bringing in Newman definitely is a good idea. But I do not expect his work to be loved. Instead he will be as criticized as much as Arnold.
(Personally, of all Barry´s successors I love George Martin´s approach the most. Fantastic melodies, a new sound, still completely Bondian.)
