How I Met Your Mother holds that title.
I actually enjoy Mad Men. I don't hold it in as high a regard as most of the reviewers seem to but I like it well enough. I actually need to finish watching it because I heard the finale was alright.
I did what I usually do with a show that's buzzed about but I haven't seen. Binge watched on Netflix and then couldn't keep up with the week-to-week.
I think a lot of people who love it to the point of calling it the best show ever are those who really like and idealize those periods in time.
I liked this scene:
It's probably not as affecting out of context, though.
Oh and I can say that it does have one of the best title sequences on television. That holds no doubt.
