1. Friends wasn't known for being the most diverse show on television at the time, since the cast was comprised of almost entirely white actors. None of the main characters were anything other than "mainstream." Even the acknowledgement of Ross's first wife Carol being a lesbian was met with jokes about sexuality (mostly from Joey), and sexist comments were frequently incorporated into the script.

3. One of the things that makes Guardians such a great superhero franchise is its sense of humor—which is full of self-deprecation and sarcasm. It's not like you're going to watch this movie and laugh your way through it, but you'll at least have some moments of "ha ha, Groot," and "lolololol Chris Pratt."
