Historicism
A historicist would celebrate That 70's Show. One reason why they would celebrate this show is because the language used in it and the clothes and decor are much like that of the 70's. For example, in several episodes, characters may refer to the police as "the fuzz." This phrase was a very common one in the 70's. They also all wore flare pants. The whole house just screams the 70's.
Another reason why a historicist would celebrate That 70's Show is the interests of the teens. As many kids and teens were in the 70's, Eric, a main character, is in love with Star Wars. Many of them also love comic books, like kids of the 70's did. Also, though it is awful, the show exemplified teen drug use of the 70's, which is very accurate.

For reasons such as these, That 70's Show  would be celebrated by historicists.
