Found one major literature review paper, how to differentiate now?
First off: Using review papers as a guide line for your review is perfectly normal. What you should consider is, that even if the review is comprehensive, since its release there has been new research and publications were released that you should address. 

Personally I don't think there is anything wrong with using review papers for tracking down other papers, but the least you can do is to also cite the review paper and remark that the review has a good take on the topic.

If you have any additions or own takes on the reviewer's opinion: do that! Discuss why you added other papers to your literature that the author neglected, give a different order to the topics if you prefer it, etc. In a historical context it might be difficult to change many things, but you should try not to copy it too much. As long as you formulate own sentences, your're fine.
