I might get some broader ideas from you guys than my friends.

Here are mine:

Orange is the New Black - if you're on Netflix you've probably at least heard of it.  I really enjoyed it!

American Horror Story - every season is basically a separate show.

The first season was a haunted house.

The 2nd was a mental institution, with some 'monsters' and someone gets locked in who shouldn't be there.  I found the 2nd season much more interesting.
