I disagree, CR wasn't a trend follower (unlike, QOS, LTK, MR and many others).
I have discussed this in another threads... The concept for the Bond origin story was around EON since 1986, particularly with Michael G. Wilson. While the so called realistic down-to earth tone for CR, was already in the earlier scripts for the Jink spin-off since 2002, and as a natural reaction to the excess of fantasy in DAD.
Anyhow, it's very probable that the producers decided that after the success of Batman Begins, it was the best moment to achieve a commercial success with a proyect that they have before, becuase of the similarities with Nolan's work.
However, a real trend follower is a work that is created trying to be similar to the one that set the trend before. Definitely, not the case of CR.
I do see where you're getting, but still, I don't think there's much of an escape that CR is Bond Begins. From what has been stated by another CBner quite a while ago on another thread who was lucky enough to have read earlier treatments for TLD, the scenes featuring a Young Bond were short and brief. And Wilson apparently wanted to tell a "Bond Begins" story at least since then, but it was at the time of Batman Begins that they decided to move forward with CR. Jinx also somewhat followed the trend of "female-lead action movies" (although I'm not sure I'd call this one a trend following per se), and took a step back when in analysis this type of movie tanked time after time (nothing to do with having a female in the lead IMHO, just "the suits" way of thinking I gather, as usual).
Having a wide variety of ideas, drafts and treatments on retainer merely means that they'll pull such aces in the hole when the time calls for it. They jumped on the "reboot the franchise/origin story" during the success of Batman Begins, thus I do consider that to be trend-following.
Still, I don't see why Campbell would be any less competent than numerous other directors that took their turns on the Bond franchise. I shall restrain from mentioning Mr. Tamahori further...
Directors as competent as Campbell can adapt, even if it's a bit by force, if so required. Taking in account his demands for the script changes in GE, and then the completely different work he delivered in CR are proof of that.
I thought they'd gone a bit bonkers for asking Campbell to come back to direct for CR, and I was taken completely by surprise by absolutely everything in the latter.
All that said, I do maintain - since story-wise QOS isn't particularly mould-breaking, wouldn't said movie have been average rather than controversial?
On the other hand, would it be so hard for Forster to have the editing toned-down a bit in order not to alienate such amount of Bond fans?
