Some tv show are not displayed in the calendar (Quantico, Minority Report).
Suits and Big Bang Theory fixed in my calendar and should be displayed now.
I can not see Suits and Big Bang Theory in my calendar, but if I check directly the show page I can see when it will air next. (maybe do an overall check for all airing shows, might be not updated yet from mid season break)
Doctor Who should be displayed in your personal calendar. We're not yet showing all shows in the calendar, only the most popular and only from US, CA (to keep the calendar clean of "not popular shows"). Doctor Who is an awesome TV Show, but it's from UK and we don't yet support all countries in full Calendar.
fixed. It should be visible right now. Check it
Doctor Who is not displayed too.
