There’s certainly interest in the fact that the Republic is portrayed as a completely ineffectual opposition to Palpatine’s rise - the deleted subplot from ROTS where a group of senators gather together with the apparent aim of stopping Palpatine consolidating power, but achieve absolutely nothing except a completely useless meeting and thus doom the galaxy to 25 years of violent resistance, comes to mind. Palpatine’s use of a scapegoat enemy he himself manufactured to justify his forever war is also notable, as is the reference to the military-industrial complex via the Trade Federation, Commerce Guild, Banking Clan etc. And of course the visceral display of inequality and arrogance in how the Jedi and Senate literally live and work in ivory towers and great domes miles above the average people of Coruscant with whom they rarely seem to have any interaction (and even further from the Outer Rim), despite suffering, crime, slavery, and so on being very prevalent. These aren’t especially profound or controversial takes generally, but are a little spicier than what most movies aimed at a similar demographic have to say.
This point is best illustated in TPM when, upon learning about slavery on Tatooine, the only one who is truly shocked and outraged is Padmé, whilst Qui-Gon flat out says they’re only looking for ship repairs and that they’re not here to liberate slaves.
