I found it very inconvenient that for writing a review i have to have a facebook account. I may be among the (probably really small) minority, but it so happens that i do not have a facebook account. I do not prefer the site at all and would not want to have an account in future too. You could use PAN numbers or other identification information to ensure real persons.

I would like to add that having a facebook account may not necessarily mean that person is real. I have seen profiles of 'people' which actually represent societies/groups on facebook.

As it is, i wanted to write a review for the benefit of all, but cannot.
