I would draw a distinction. There are churches that are old and in disrepair; there are churches clearly built on a limited budget. Yet often they look and feel like a church because they were architected with worship in mind. Then there are those that indeed look like municipal buildings or airplane hangars. It is not the opulence but reverence that makes the difference.

Forgot one more category: pretentious architectural "wonders" with designs intending to reformat the very concept of a church building. Some don't seem to be lacking funds. Many would be lovely as shopping centers or concert venues; many don't seem to have any obvious purpose.
