While my primary wish would still be something that targets novels ("Learn enough Italian to read Eco"), something similar for TV shows wouldn't be that bad. Preferably not a dubbed version, so that it's clearer that you've already got a benefit from learning what little you did. Problem is that a lot of TV shows are very much in the vernacular. I wouldn't recommend e.g. the Wire for ESL studies.

I learned a lot of my early English from reading tabletop RPGs, so I've got no problem learning about twelve kinds of polearms before I learn the words you need to get by in a hotel…
