The clueless plot behind such a classic movie

The 90'c classic 'Clueless' is one of my favourite re-watchable movies. However, the more I watch it, the more questions I have regarding the plot. What was the point – was it to follow Tai's journey to a new school, was it to follow Cher's love life, was it to watch Mr Hall and Ms Geist's romance blossom? The multiple storylines aren't overly complicated and all seem resolved in the end, but it just leaves me wondering. I doubt I'm putting too much thought into a movie that can blame this mess on being out-dated, as we saw Iggy Azalea's imitation of the film in her 'Fancy' film clip in 2014 and the world was shocked by the film's Brittany Murphy's 2009 death. Was this simply the style of a fun 90's film, or for that matter the comedy genre – to fill it with multiple storylines in order to keep it fun, light and entertaining? And if so, why is this plot-messy classic the one we still remember today?
