It's just entertaining. After every episode, I could just laugh heartily at whatever stupid antics Lelouch or somebody pulls off and then wish for a Milly x Lelouch end. It's just fucking entertaining, and that's all that matters. Who cares if some people say it has shitty writing, who cares if the Euphinator was a stupid plot device, who cares if V.V. is not a girl? Only trolls. All that matters is that it entertains you. From table humping to Norio Fucking Wakamoto, this show never fails to deliver everything from RAGE to lulz.
Of course, this doesn't apply to some shows like Naruto because it's not entertaining and shitty.
