I never watched either show when they first came on tv (E.R. in 1994 and Dexter in 2006). Both were critically acclaimed. E.R. won dozens and dozens of awards during its 15-year run and is generally thought of as one of the best medical dramas ever created. Since we just started watching E.R. a few days ago and we've got 15 seasons to watch, it's gonna take us a while. We just started watching season 8 of Dexter and that's the last season in the series. When we're done with that, we will watch Dexter:New Blood which takes place 20 years later and ends the saga for good. .We're still working on The Big Bang Theory. We squeeze in a show every now and then and have managed to get through almost 10 of the 12 seasons.
