The series finale was quite a powerful episode in my opinion. During some of the scenes I couldn't help but tear up especially when for example Norman has his breakdown with reverting back to the past. Or the scene where he wakes up as if he never killed Norma. And of course the scenes with Romero before he died as well as the scenes with Dylan's phone call to Emma and then with Norman. Only one other Bates Motel episode ever really made me feel this intense of emotion and it was the previous finales scene where Normans about to realize Norma is gone but then mother appears and it's christmas suddenly and his delusions begin.
