Have you considered _.reject?

From the underscore documentation:

Returns the values in list without the elements that the truth test (iterator) passes. The opposite of filter.

var odds = _.reject([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
=> [1, 3, 5]

You probably want to use filter http://underscorejs.org/#filter

fools = _.filter(fools, function(user) {
    return !user['great'];
});

Or reject, which is just sugar.
