3. Old Rebecca looks ridiculous. This has actually been an argument my mom has had since season 1, but it resurfaced thanks to new gripes with the NBC series. Personally, I think that This Is Us does a fantastic job making Moore look like she's in her 60s (Moore, in real life, is even younger than the stars who play her children), but my mom insists that Rebecca looks like she's in a school play. What does this say about the production quality of my high school musicals? I'm not really sure.
