I would just create a custom filter. They are not that hard.

angular.module('myFilters', []).
  filter('bygenre', function() {
    return function(movies,genres) {
      var out = [];
      // Filter logic here, adding matches to the out var.
      return out;



<div ng-init="movies = [
          {title:'Man on the Moon', genre:'action'},
          {title:'Meet the Robinsons', genre:'family'},
          {title:'Sphere', genre:'action'}
       ];" />
<input type="checkbox" ng-model="genrefilters.action" />Action
<br />
<input type="checkbox" ng-model="genrefilters.family" />Family
<br />{{genrefilters.action}}::{{genrefilters.family}}
    <li ng-repeat="movie in movies | bygenre:genrefilters">{{movie.title}}: {{movie.genre}}</li>
