It's almost Thanksgiving, which means it's almost time for mid-season finales to take over the airwaves. The "This is Us," mid-season finale airs tonight, on NBC, at 9 PM. Fans have been waiting for "the Big Three" to see each other once again and it seems they may finally all come together for Thanksgiving in Philadelphia. As excited as fans are to see the Pearsons all together again, there is a little disappointment about how early the show is coming to a halt before the holidays. Last year the show didn't put a stop to the drama until much later in November.
