Many people were probably exposed to shounen first and most likely something like DBZ, which causes people to stereotype the genre as something that is ridiculously drawn out and filled with filler, though certain other popular entries certainly haven't helped with this image. On the other hand, it may just be because a lot of people are falling out of the intended audience range.

Though asspulls are hardly unique to this type of show.

Personally, I guess my experience with it has never been the best; I've never been one to be able to keep up with large series and the manga is just frequently more entertaining. If you complain that DBZ takes ages to end a fight, just flip through the manga. Certainly shows like Yu Yu Hakusho, HnK, or Hunter x Hunter are more fun, but they tend to be the exception to me.

On the other hand, the most common shounen tropes tend to have a strong relationship with classic video games and leads to great moments in both, so it's not like I can really dismiss any of it as bad, as long as it isn't overdone.
