I have to agree, it just isn't as good as it used to anymore.
People have been saying "oooh look, South Park dumped on Trump, they sooooooo back! yeyeyeyeyeyeyeya!" I thought it was funny, but then kinda fell out of it after a while because it just seemed very desperate of them to gain viewers after their fall-off. Heck, anytime they make fun of anything, it's a desperate ploy to get viewers back, because they know they don't have a single good or original idea. They can add a bit of satire throughout an episode or a whole season, because it's a PART of the whole formula of the show, not the WHOLE show.
