A word I accidentally mumbled in class: "crudimentary." I think it means both rudimentary and crude. Anyway, I like it, and am going to try to start weaseling it into as many talks as I possibly can. Speaking of which, here are slides for a guest lecture I gave to the local alternative models of computing class at UW.
With a little modification, we have "crudumentary" - a documentary that is crud.
I can imagine T. Bruce McNeely's suggestion leading to this one-line review:
"The crudumentary 'Expelled' is craptacular!"
