To be fair, Antonescu was probably the first non-extremely corrupt leader the Kingdom had for over 20 years. The Liberals were a bunch of kleptocratic scrotes, and the National Peasants brought about Carol II's (unconstitutional) restauration.
His one true sin was his sycophancy towards the Germans, which led to hundreds of thousands of dead Jews and Roma and the Kingdom's embroilment in Operation Barbarossa (though it's debatable whether the Germans would've allowed the Romanian Army remain at readiness, since they never fully trusted the generals under Antonescu, several of which tended to have pro-WAllies sympathies).
At any rate, any 1944 PoD must start a lot further back, namely during the Great War.
Antonescu wasn't Teutonophillic, he avoided working with them until the Soviets started knocking on his door and no one but the Germans was there to help. Thereafter the Romanians conducted their own Holocaust independent of the Germans, Germany didn't request them to do what they did, so they have the distinction of the only country to willingly conduct their own Holocaust during WW2.

They tapered off in 1942 and Germany pressured them to continue, but they started on their own.
