Multiple levels of thoughts.
Socially - good for them. They've managed to hold things together and maintain something resembling a healthy society significantly better than most others in the west. Maybe still not great and not without internal flaws, but the results speak for themselves.
Theologically, they get a LOT of shit from other Christians. Mainly over stuff like the Trinity, or lack thereof. Typically, the more serious a Trinitarian Christian is, the more they despise Mormonism, especially the Tradcath and Orthobro faggots. I find this to be pretty despicable. Most Christians are perfectly fine calling the Trinity "mysterious" or mystical or even actually unknowable because God or some shit. I personally don't have a problem with this - good for you for having the honesty to say "idk lol", spirituality is hard after all. BUT to me, the flipside of that is that means you don't get to shit on others that actually stake a more concrete theological claim like the Mormons do. I mean you just said you don't know, how can you shit on others that think they do?
Plus theres some surprising gold in there about stuff like you literally becoming a God after death and other stuff. It does start to diverge from traditional Christianity in big ways - ways that as I have distanced myself from my personal theological upbringing, I've been more open to, or at least view as less out there.
Anyway, I do still see them as rooted in Abrahamic/Yahwist shit, so I still overall see them negatively. But I've grown more sympathetic in recent years. They are misrepresented and maligned by both the ridiculous ultra-Christians and the faggy atheist South Park loving types, that makes me feel bad for them. If I had to "convert" to some Desert Cult church, they would probably be it, because fuck it, they keep themselves together and their women are at least skinnier and probably freaks in bed with their future literal God-husband.
