Sometimes this show takes a dip into over-cliched, but it has a somewhat realistic portrayal of high school in contrast to most high school portrayals. I also like how they look at teacher culture as well. I really like it when they get all quirky. The only episode that's disappointed me was 2.
Also, right now I like Quinn more than Rachel.
She's got more layers, especially with the line at the end of episode 3. She's also insanely pretty. Like, Yoona-level pretty.
And any show with Chenoweth in it, guest star or no, is win.
