Meh, I've never given a damn about her, I did like the first episode she appeared in in X-Men:Evultion bu it would have been just as enjoyable with anyone else substituted for her.
I do enjoy the fact that since she's just a clone of Logan they've pretty much, entirely unintentionally, shown that both characters are bisexual. How else could two characters with the same DNA (though I believe X-23 is issing the Y chromosome only) both have interest in the opposite gender? Either 23 should have been a lesbian or they're both bi, not that the writers thought of that.
