I hated clones before Umbara. I figured, what's the point of getting invested in cheap, identical and expendable foot-soldiers that the show kills off like flies? However, in hindsight, I wasn't paying any attention to the many subtle (and some major) differences in each clone's personality and what made each one of them more unique then their identical-looking brothers. But then I saw the glorious Umbara arc, chock-full of interesting clones that showcased such a stunning variety of clone personalities and individuality that is caused my perspective to completely change. Now I take great enjoyment in studying each and every major and minor clone on the show and trying to decipher what makes each one tick (of particular interest of course is Rex, and I found myself more invested in his fate than ever before). I now pay ever more attention to seemingly unimportant personal details like armor markings, tattoos, hair styles and personalities that I never even noticed before, and because of it I now fully enjoy their presence and nothing short of a clone-centric arc like Umbara could've accomplished that.
