I think when it comes to a love triangle, the bad boy type is always more appealing to me. But he has to have a deep and complex personality, not just the look and actions (aka dark and wears edgy clothing, rides a motorcycle, etc.). A one-dimensional bad boy without something compelling or heart-warming about his personality is just a thorn in my side.

If we're talking the Grisha trilogy though, why not THE DARKLING?? Possibly the baddest bad boy of all time, and the most compelling! Let's be honest -- Mal is a pretty darn boring and plain choice in comparison. I wonder if I might like him more if I reread the trilogy again, knowing that she ends up with him.
