this is obviously a multifaceted/multiparametric issue. I'll touch only one - nationalism. Marie Antoinette was perceived (whether it was real or not) as siding with Austria and against France through her years in France. That is not a way to gain a public support/love to say the least. Compare that with the contemporary Russian Empress Catherine the Great who also came to her future motherland as a foreign (German) teenager girl to marry the future Emperor. Russian history has her as "Great" and her rule as "Golden Age" even though, among the other things, she did put violently down a large peasant revolt and was overall a tough absolute ruler over highly unequal society - very poor and powerless majority of population under highly privileged aristocracy. Yet her policies and actions were notably pro-Russian and directed to, and very successfully at that, - using the language of today - making Russia great (especially for the most nationalism related definition of "great" like huge expansion of the Empire in all 4 directions mostly as result of successful application of military power or threat of it). Thus she is a great/popular Russian Empress despite her lifetime German accent (which she had despite her eager learning of Russian upon arrival), her famous promiscuity (be it true or not), "accidental" death of her husband Russian Emperor Peter III during her power taking coupe, etc. - i.e. it would be possible to find a lot of reasons for the hate if it were needed. The nationalism is kind of very primal overpowering force, which can bring extremes of popular love or hate. https://en.wikipedia.org/wiki/Catherine_the_Great https://en.wikipedia.org/wiki/Catherine_the_Great
