Magento 2 – Get Product Details in Product Review List

Finally I found the answer for my question. :)

Step1 add this code on local.xml

<catalog_product_view>
    <reference name="content">
        <reference name="product.info">
            <block type="review/product_view_list" name="product.info.product_additional_data" as="reviews" template="review/product/view/list.phtml">
                <block type="review/form" name="product.review.form" as="review_form">
                    <block type="page/html_wrapper" name="product.review.form.fields.before" as="form_fields_before" translate="label">
                        <label>Review Form Fields Before</label>
                        <action method="setMayBeInvisible"><value>1</value></action>
                        <action method="setElementClass"><value>rewards</value></action>
                    </block>
                </block>
            </block>
        </reference>
    </reference>
</catalog_product_view>

Step2 Call it from view.phtml

<?php echo $this->getChildHtml('reviews') ?>

Maybe it will be helpful for upcoming newbies like me in the future :)

Below code may help you.

$_productID = 101;
$_product=$this->_objectManager->create("Magento\Catalog\Model\Product")->load($_productID);
$_review=$this->_objectManager->create("Magento\Review\Model\Review");
$_reviewFact=$this->_objectManager->get("Magento\Review\Model\ReviewFactory");
$_reviewFact->create()->getEntitySummary($_product, 1);  
//Below code will get the rating summary
print_r($_product->getRatingSummary()->getRatingSummary());
