Agreed...Plus don't forget Sopranos... I love going to the movies and go all the time, but you can tell a difference in the quality of TV programming like 24, Heroes, Lost, etc...I still wish Rome wasn't going away...
The same argument about what is POPULAR versus what is GOOD could be made in music. I hear people all the time say, "There just isn't any good music out today." That's bull****. There's plenty. You just have to look for it. The same goes for film. There are plenty of good films being made. It's just that most of them aren't big-budget, mass marketed Hollywood blockbusters.
See, I think all three of the non-HBO series you listed have their share of terrible acting, especially Heroes. Actually, I'm not sure there's a decent actor in the bunch.
