The line in question is this:

$data =  Mage::getSingleton('review/session')->getFormData(true);

This means that Mage::getSingleton('review/session') returns null (or false).
Check if you have the file app/code/core/Mage/Review/Model/Session.php exists.
If it doesn't then get it from a clean magento instance.
If the file is there, then most probably there is an extension overriding this model and there is no way to guess with the info you provided what's the problem.
