I think it also depends on the genre. If you're writing, say, urban vampire stories, everyone knows more or less what a big city looks like -- if only from depictions on the TV -- so there's no need to dwell at length on big skyscapers and yellow cabs and what people are wearing, and a few mentions of specific things will allow the readers to fill in the blanks. But if you're writing hard SF, then almost certainly your readers will want long loving descriptions of all the space craft/alien habitats/life suits and how they are powered and armoured and weaponed and *yawn*
I'd say soft SF needs less description of the hardware, but a novel set on an alien planet needs sufficient description of everything to convey its alien-ness. Similarly high fantasy requires some idea of landscape, clothes, food etc to give the reader some feel of what type of age and country it is and how it differs from C21st life. There has to be some grounding in the environment, natural and/or man-made, to allow the reader to inhabit it.
I think the main problem you might be having though is shown in your comment about "long boring descriptive passages" -- you might find other writers' passages to be boring, but your job as a writer is to ensure that your prose never is! I've not read any Matthew Reilly so I can't comment on how he writes, but if you aspire to write like him, the first thing to do is analyse how he holds your attention within a scene, and then try and copy his technique.
When it comes down to it, though, some people like a lot of description, some hate it, some like lyrical passages, some want plain information simply told. Match style of writing to genre and likely reader expectation
