IMHO this isn't a good task for the Turks. If it's reasonable that a Turk might click 'Looks good to me!' most of the time, you'll gather a hoard of them that just click/script that same response 100% of the time and not look at the question. Of course you can include decoy questions to try and detect this behavior, but I just don't see the whole MTurk review process being terribly reliable overall. I just don't think the worker quality is that great, and they will do whatever possible to just churn through HITs (because they get paid zero for them).
