SNL's celebrity stunt-casting points to a larger problem with the writing

"I don't have strong feelings about Jim Carrey as Biden," says James Poniewozik. "Maybe he'll be good! But continually hiring outside stars for big roles just underlines how SNL is more concerned with the *impression* of the person (voice, likeness) than the *idea* of the person (writing, character) In other words, if you have a good writing team and a good cast and a willingness to *actually say something with a point*, you wouldn't be so concerned with "What celeb would do the best impression of ___?" (But this has been true for a long time.)"
