+1 for me.
I loved the way TVrage.com allowed filtering on their calendar page. It was MUCH more useful than ambiguous genres. They had (if I can remember) Scripted, Reality, News, Talk show, Specials, Mini-Series, Sports, Documentaries, Childrens, Other (such as Comedy or Game shows). (They seemed to only list shows aired during prime-time, so maybe a Daytime category would be helpful here.) If anyone has a better memory please chime in.
TVrage also had a country filter on the same page.
I would love to see similar filters in NE on the Home, Episodes, Calendar, Browse, Top Charts, Watchlist, TV Schedule, and Discover pages. Basically everywhere possible.
To be clear I am talking about filters that include only the selected label and exclude the others. I suppose you could allow multiple labels to be selected if it doesn't clutter things up too much.
