How likable should protagonists be? Do unlikable protagonists need some qualities about them that readers can identify with, some aspect of the character they can feel invested in?
It’s a debate I’ve had with a number of other writers. While I think there are no right or wrong answers — there’s a reader for every kind of writer — I lean down on the side that even unlikable protagonists should have something about them that helps readers root for them in some way. Even if the protags are horrible human beings.
In that vein, I stumbled on this excellent video blog from the Lessons on the Screenplay channel on Youtube that examines the protagonist in Nightcrawler, a tremendously underrated movie. Jake Gyllenhaal plays a true sociopath in it, someone who I highly doubt most any viewer could actually like, who is yet an incredibly compelling character. The performance is a tour de force, but it’s all there in the screenplay, too.
The video really sums up my thoughts on the subject better than anything I could write, and uses great examples from the screenplay for evidence. I hope others will find it as useful as I did.
