That said, "large and angular" fits his style pretty accurately. Though the most indicative aspect of his designs is the layering. A lot of his buildings are built to have a very particular look of being made up of mostly flat horizontal layers of various thicknesses, protruding or retracting from the layers below them in varied shapes. Often these leaned heavily into having a lot of right angles, but when he used curves, he leaned hard into them: The Norman Lyke's House or The Center for the Performing Arts in San Jose are example of extremely curvy buildings still unmistakably in his style.
Ultimately, Wright's enduring fame can be easily understood by the fact that he was novel, consistent, and prolific. His style was (and to only a slightly lesser extent, still is) new and different from most everything else, and he stuck to it enough that people could recognize his work in particular. Combine that with designing quite a few buildings, and you've got yourself a recipe for the most famous architect ever.
The I love Lucy show changed the TV industry. It is the first TV show made with archival quality footage, on some kind of reasonable schedule for the actors to have a life, invented the rerun and many of the basic techniques still used today in the industry.
The people who radically alter what was tend to be revered but those who come after and grow up with the heritage of what they fostered often take it for granted and don't get why it's special.

I like them (the ones I've seen anyway). They have an interesting and unique aesthetic. I like the design of the stained glass alot. I'm not sure how practical living day to day, but people did. The one in New Hampshire (Zimmerman house) had wall to ceiling windows on the back side.
This is a fun use of 3d tech. I did some Unreal engine work, and the first thing was building out an apartment interior you could then move through in real time. It was kind of neat. The detail in having to place all the interior lights and all was something.
The "Groupius House" (by walter Groupius) is another modern really practical house. But in this case the architect was the ocupant.
Look at photos of the Robie house in Chicago, typical of his early prairie period:

The largest building of his prairie period was the Dana-Thomas house in Springfield, also worth seeing.
Here is a very well done KCET documentary that explains more.
