You know, the best sitcoms, the best music, the best anything, tends to go unnoticed in this day and age, when mediocrity is so often rewarded by the masses and the corporations. So to find the gems you have to do your homework and shift and sort and use your discernment.

So I don't see any issues with modern comedy, you just have to look for it. Talent has never gone away. Of course if you look for it in How I met your whatever, you are going down the wrong path. But that's just my opinion.

Edit: Wow, you are downvoting me and I didn't even say that How I met your mother is just pure crap.
