Sure, but saying that one prequel was more disappointing than another seems a little strange to me. For some reason I’ve started to think of the PT a single entity rather than three individually released films. I don’t think of the OT that way.
ROTS at the very least has things happening during most of it. AOTC is one of the most boring films I’ve ever seen. All the PT is pretty boring to me, but AOTC more than any of them.
