I'll be honest: each year I struggle with saying goodbye to my favourite TV shows before their Summer hiatuses. I mean, as an unabashed couch potato, what else will I do during my leisure time? ABC, NBC, Fox, CBS, The CW, and FX have already announced the season finale dates for their TV lineups, and you hear that? Yep, that's the sound of my heart splitting in two. Fan favourites, including Once Upon a Time, Homeland, and Shades of Blue won't return in the Fall. On the bright side, many of the titles ahead will be back just in time for sweater weather. Keep reading to see when the final episodes will air for shows like The Flash, Grey's Anatomy, and Roseanne, then check out all the new Summer shows you should get acquainted with in the meantime!
