Comments?

So ... is it possible to render a comment form (that works) for a nodereview node type? (does nodereview even do comments?) It would seem the 'normal' way of doing this in a node template does not do anything useful. Is there a way to call the comment form in the template that I'm missing? I could use an example of how to do this. Please help!

I've tried
print drupal_get_form('comment_form');
which I think would be the normal way to accomplish this.
I've tried a few other things too, but I'm really just not getting anywhere.
