Personally I do like code geass as a whole, from the plot the knightmares and the Dynamic Duo of lelouch and CC, oh and Rolo as well, sadly I don't majority of the casts there like Ohgi, Suzaku, even Kallen (sorry)

Well I don't like Kallen so high five! @RanmaXUkyo

hate the entire cast of blood+ but thing the show is solid (ish)

Yep. Hate 100% of the characters in Sword Art Online, but the show itself isn't all that bad. Stillnot good, but it would be a much better show if the characters weren't so awful.

I usually don't care enough about characters to hate them. I'm just indifferent to most of them. So, no.

Nope. If I hate most of the characters, the anime would be dropped. It's a reverse for me. I have watched anime where I liked the characters, or a specific set of characters. So I watched for them, and cared about their personal stories, but not for the series' plot as a whole.

The only way I could get through an anime that I HATE most of the characters in is if the one or two characters I actually liked were ABSOLUTELY AMAZING!

Can't say I do. A series just wouldn't be worth watching if I hated a huge majority of its characters despite having a good plot. I'd enjoy it a lot less to be honest.
