The Sopranos is simply a masterpiece, not much else to be said there. I watched all the seasons with my Father in about a week.I'm a big fan of most of the HBO and Showtime series. Here's a quick list of the things I've watched recently that I enjoyed, and yes I know there are some old series on here.
Sons of Anarchy
The only real sitcom I watch is Always Sunny in Philadelphia. Probably my all time favorite is The Shield. The last season that just concluded with the series finale is off the charts good. From the first season to where it ended, that show went in a ton of different directions.
I have been watching The Shield for about two months now and I prefer The Wire, but I still enjoy it. Got given the first series for free by a friends Dad that didn't like it... so it's all good there.
I like your taste in TV, Abe. And yeah, HBO do some very good TV.
