The best thing that clone wars ever did was humanize the clones and make them deep characters. Through the show, there has been a lot of development in 2 clones in particular (rex and fives) who have been the centre of many arcs. This final arc with fives is a brilliant one where he even discovers palpatine's identity before a single jedi. A true testament to how undermined the clones are by the jedi and how clever they can be if given the opportunity.
