It's so slow: on the order of single digit minutes to a dozen to install a single package. It feels messy, like it's shotgunning my entire system with bits of itself (I don't know how true the reality of this is). I've not infrequently had packages simply fail to finally resolve after they did their dance of resolution. It does not inspire delight. The vibe, if you'll excuse me, is very crude cudgel.

Oh, the install location it asks you about when installing Linuxbrew is extremely odd. One choice offered is to make a dedicated brew user directory and then install there? That's terrible practice. No one else does this because it's terrible. And then the other apparently breaks a bunch of stuff and is not recommended.
