I was musing on this question in bed this morning. I’d just woken up from one of those dreams where you’re in class, but haven’t done your homework.
Tthe only recent college/university shows I could think of are Felicity and the genius that is Tommy Lee Goes to College. I don’t know a lot about television production or show selection, but you’d think there’d be more of these. After all, don’t most people remember university favourably?
I suppose duration is an issue. If you’re going to adhere to current practice, you can only justifiably have the same cast for four or five years.
