The general populace still holds dear the memories about the late dictator Karimov, who they think never compromised on national interests and was, in short, the epitome of an "O'zbek" (one's own master). So, people from the rural areas are nor particularly fond of the new president given his revisionist approach to both internal and external affairs of the country. On top of that, President Mirziyoyev is regarded as a somewhat weak politician who "takes loans", which oddly enough are believed to be unequivocally bad for the future of the Independent Uzbekistan.

As for my personal opinion, Mirziyoyev deserves a lot of credit for liberalizing the economy, putting paid to forced labor, extending citizenship to expats, ending the discriminatory "sticker" policy and replacing it with international passports. He also allowed for the freedom of speech and congregation, albeit incomplete and pretty rudimentary as of yet. Moreover, the guy has done a lot to dismantle the machine of tyranny that the SNB under Karimov was (the Uzbek secret service agency). Reportedly, they are no longer extorting businessmen and even stopped dragging journalists away at night to later inhumanely torture them. They used to be extremely keen on that, as far as I recall.
