Why won't my taxonomy query show up?

I’m attempting to display posts from a ‘Uncategorized’ category under a custom taxonomy called ‘Reviews’ but without much luck.

I’m using get_template_part('loop','review') to call loop-review.php which contains my taxonomy loop but for some reason, nothing will show up. What gives?

Here are the contents of loop-review.php:

<div class="row no-margin detail">
        <p class="title"><span>reviews</span></p>
        <?php 

        $args = array(
            'post_type' => 'page',
            'tax_query' => array(
                array(
                    'taxonomy' 	=> 'review',
                    'field' 	=> 'slug',
                    'terms' 	=> 'uncategorized'
                )
            )
        ); $review_query = new WP_Query($args); ?>
        <?php if ($review_query->have_posts()): ?>
                <?php while ($review_query->have_posts()): $review_query->the_post(); ?>
                        <p class="quote">
                                <?php $review_query->the_content(); ?>
                                <span><?php $review_query->the_title(); ?></span>
                        </p>
                <?php endwhile; ?>
                <!-- end of the loop -->
                        <?php wp_reset_postdata(); ?>
		<?php else:  ?>
                        <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
		<?php endif; ?>
    </div>

Lastly, here is the code from my functions.php

add_action('init', 'build_taxonomies', 0);
    function build_taxonomies(){
            register_taxonomy('review', 'post', array(
                'hierarchical'    => 'true',
                'label'           => 'Reviews',
                'query_var'       => 'true',
                'rewrite'         => 'true'
            )
        );
    }
