I think my favourite shows were from the 90s. Frazier, Friends. But, there are also good current shows like The Big Bang Theory and How I Met Your Mother. As always, there is crap but every single decade has had bad TV shows.
With movies, some are good and some are not. Just like in the past.
Movie quality is going down because they're running out of origional story lines. Remakes are more common than in the 90's. There are still some good one out there though.
While there are some creative ideas for origional shows since 2000, there are some really dumb ones out there. too many reality shows that show people going about their lives with no point to them except to make them famous. That's why it's been ruled that reality stars cannot have a star on the hollywood walk of fame. I agree with that.
At the place I live, I have 19 digital channels for free with 10 buck's digital antenna and a digital converter to my old small TV. Picture is perfect. Enough for me, I do not have time for TV, but digital image is very nice even on an analog TV. I love it! To answer the question: I think we have both good and bad shows and movies, as always.
