Bidet of Evil
Without comparing BtVS to any other show, it can easily be seen as shallow.
It's almost like it has great writing and the writers hope that the cleverness of their writing will overshadow the fact that there is not really any series-long storyline.
I would say BtVS is like a fancy-looking machine with all the bells and whistles but does not offer much.
Comparing it to Charmed however is a bit unfair since Charmed had some pretty crappy writing but the storyline is there through the entire series. Charmed is like a computer tower...you can have a real dull look to it on the surface but the real workings of it take place inside--and if you don't want to go deep, you'll come away not impressed.
Back to Buffy's show:
The writing is great but apart from season five there is no real storyline.
It's the writing...and that's it.
So if people do find Buffy shallow, it's probably due to that.
You think there's no underlying narrative arc?
Season 1, I will grant you, is episodic in nature. The events in season 1 lack a cohesive narrative arc. Season 2 had much more of an arc, this based primarily on thematic content. Seasons 3 - 5 all had a "big bad" to provide a very stable narrative arc for each of those seasons. Season 6 was structured much more like Season 2, in that its arc was based on thematic content. Season 7 looked like it attempted to have a cohesive narrative arc, but I think it failed. The writers tried to place too many disparate elements into play - especially at the last minute - and so the result was a jumble. The narrative arc of the entire series was Buffy's journey from adolescent to capable woman, hence the symbolic destruction of her adolescent home at the end. Coming-of-age stories may be done all the time, but that doesn't mean they aren't stories! What I see in Buffy is a coming-of-age story presented in seven parts. Each part is like one volume of the series. Some of the volumes are better written than others, yeah, but Buffy has a narrative arc similar to that of Harry Potter or the Hornblower series or anything out of Dickens. I'm not saying it's as good as Dickens, mind you, I'm just saying the structure is equally as valid.
