Between TRT, steroids, HGH, and vaping (certain flavors cause heavy metals like lead, mercury, cadmium etc. from the coil/atomizer to leech into the e-juice) he's definitely not quick on his feet comedically any more, and then there's the fact that he's surrounded by a bunch of yes men that have inflated his ego to the point where his sketches aren't even edited past stitching shots together. Most of the new "MDE" stuff with Nick is 10 minutes of filler around maybe 3-5 zingers. The WP "you tripped my wife" sketch and the gumroad vineyard sketch is a perfect example of this.
You know what after writing the above the biggest problem is the length of his sketches. HWD was genuinely funny most of the time, even if it also suffers from the filler/length issue to a degree, and a small degree at that
And unrelated, for someone who's supposedly obsessed with how video looks, his team is doing a shit job with that stuff. Their encodes are full of blocking artifacts, the video is over-sharpened, the grain doesn't match any sort of film stock I've ever heard of/seen (and if I was autistic enough to check it probably doesn't even match the frame rate of the video underneath it. I **am** however autistic enough to notice that the image underneath the grain should be softer and slightly warmer when you're trying to emulate actual film), and everything is over-exposed or has the contrast turned up WAY too high. If the fastest CPU in my household wasn't an AMD FX 8350, I'd do all of the post editing stuff like color grading, simple VFX like grain and other film artifacts (for lack of a better word, I mean it in a positive way), and encoding myself FOR FREE because it looks like such a shit attempt at "high quality" video. I probably have more experience in this area because of my fansubbing (I had to deal with encoding shit DVD releases and raw Japanese transport streams that changed interlacing schemes and frame rates every 10 minutes) and private tracker days than any of the crew, Sam included, anyway, And why can't one of his zoomer slaves hold a fucking boom mic? Why do I have to be subjected to shit audio when I'm paying for this shit (I'm not but I did for a good while)?
tl;dr he's never been the sharpest tool but managed to strike gold in terms of "getting" the zeitgeist of a certain era, but then he went full meathead and cares more about clout, money, cars/bikes and being worshiped by people 20 years younger than him
