I drew this after reading David Cross's reasons for doing Alvin and the Chipmunks. I can't really see why anyone would get angry about him doing a movie to make money. Most of my paying work has been on projects I've either been ambivalent about or outright disliked. When I wasn't spending free time on other creative endeavors, this used to really bug me. Now I realize there's only so much I can do about the overall quality of paying projects, and that I should use my time on them to save up money for personal work, and to find something about the actual work to enjoy and use it as an opportunity to stay sharp and improve so that I'll be that much better on the work that I do care about.
Anyone calling David Cross a sell out must be lucky enough to have a job that pays them very well to do exactly what they love.
