Display a specific category in a focused area of my site

I've been trying to change the code of my WordPress site. Rather than showing trending posts which is determined by post_views_count, I simply want to show posts from a certain category. The code, as it stands is:

if ( !function_exists( 'getCrunchifyPostViews' ) ) {
function getCrunchifyPostViews($postID){
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return 0 View;
    }
    return $count.' Views';
  }
}

if ( !function_exists( 'setCrunchifyPostViews' ) ) {
function setCrunchifyPostViews($postID) {
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
  }
}

How can I simply get it to show posts of a certain category? (FYI the category_name is 'review')
