Eh, I’ll always hate ROTS over the other prequels; no amount of darkness can ever make up for the shitty execution of Anakin’s fall, that sorry excuse for a Jedi Purge, and Padme’s continuity-violating death.
I think the reason ROTS was so awful was because AOTC was so inconsequential to the overall plot of the PT. Had it perhaps painted Anakin as a noble Jedi who was gradually slipping over to the dark side then ROTS wouldn’t have seemed so rushed and stupid. I can see why you hate more than the other two, I just think that AOTC (and TPM also) are to blame for the disastrous storytelling in ROTS.
