It's ABC's highest rated show on Sunday night. It's pretty much safe. Plus it's the number 1 show of the timeslot with young adults across the board. So thankfully the show is actually on quite a solid ground because its fanbase supports it so much.
I don't think this show will be cancelled abruptly--if anything, they'll give it a final season. If a show has made it to season five and still has a massive following on a SUNDAY, it is definitely safe. I really don't want this show to end, but I know that it'll be done really well.
I'm so excited This
sneak peek looks promising, so they better deliver
This show will not be cancelled anytime soon, unless the ratings plummet, but I doubt that, plus it gives ABC way too much syndication money to be cancelled at this point.
