In the millennial suburbs some people have converted their garages into small indie move theaters with good sound systems and people from around the neighborhood show up to watch obscure movies together and eat barbecued food.

pre-millennial here; we call this a party, rather than a "suburban prosumer boutique theatre".

Is this actually a broad trend, or more just your personal experience? There is very little that could get me to move back to the suburbs, but this kind of thing is compelling.
