This two-pack is an amazing pairing of like-minded high school comedies that are also suitable contrasts in that "Fast Times..." was generally a contemporary "classic" defining of its time (the frosted-blonde locks and Vans sneakers found their way IMMEDIATELY even to my burg of an Atlanta suburb high school in Lilburn, GA and fostered a class of Spickoli wanna-bes), whereas "Dazed..." was essentially a nostalgia piece, a throwback film designed to recall another time entirely.
Both films do as fine a job of depicting the reality of high school life as being equally dismal and comic, categorizing the cliques that were more specifically targeted in the John Hughes films of the 1980's as being less than specific sub-groups than being variations of the same theme; we're all somewhere between childhood and adulthood, and we're all equally screwed.
Both films are also similar in that they highlight the performances of actors who would eventually become well-established within the industry (even going so far as to win an Academy Award in Sean Penn's case) in the early stages of their careers; Sean Penn and Jenifer Jason Leigh in "Fast Times..." and Ben Affleck and Matthew McConaughey in "Dazed...", to say nothing of the actors in smaller roles (Nicolas Cage and Anthony Edwards in "Fast Times..." and Parker Posey Milla Jovovich in "Dazed...", just to name a few).
As a suburbanite old enough to remember both eras covered in these two films (I could've been anyone's little brother in "Dazed..." and could've passed for Mark Rattner in "Fast Times..."), I can heartily vouch for the authenticity of both movies as well as the competance with which both screenplays were written. The performances of all the actors as well as terrific soundtrack scoring in both films make this two-pack a no-brainer; both films are absolutely worth their price and should find themselves in the collection of anyone who thinks that the "American Pie" series is the perfect representation of young adult life in America. Both of these movies showed it first and portrayed it better.
