you reckon I could put noindex on each review page and then just wait for Google to de-index them?
if you drop robots.txt it shouldn't be necessary
Sorry, didn't quite get this bit...
To clarify my last comment, if you don't use robots.txt, Google will remove the page from the index... and requesting manual removal won't be necessary.
Also, make sure you don't use "nofollow" in the meta robots noindex.
