Why does this movie get so much praise?

I recently went back and watched this movie again and I don't know why it gets so much praise. Sure the movie has a killer costume design and it is acted well but the Dialogue is both great and terrible at the same time. Watching it now makes me realise more of the jokes and references they make in the movie but a lot of people younger than me won't know a lot of what they are talking about.

That and the high superficial nature of the movie is pretty annoying. My favourite character in the film is Josh because he is the most "Normal" in the movie and I guess I like Paul Rudd. Don't get me wrong Alicia Silverstone does well as the lead but why is she the only character to get any real growth and development in the film? It also annoys me that a lot of the drama and problems in the film are silly, like diving on the freeway, and the more serious ones are played down and not spoken about like being robbed.

I go into greater detail in a video I made if you care to watch it.
