I found a clip on Youtube from the mid-80s that had Chris Chibnall criticizing Pip and Jane Baker for their contributions to Doctor Who, calling their stories "runarounds on a space ship". What I find funny is that his first contribution to Doctor Who, the episode 42, is exactly that. His Torchwood episodes aren't that much better.
I'm reminded of stones and glass houses...
However, expect the new series to get progressively more American, as it's unfortunately been a big hit in the States somehow.
If, by American, you mean more like the X-Files, then I say go for it.
