I've now watched the entire Skywalker series in the space of about 10 days.
My first rookie mistake was thinking the episodes were numbered in the order they were released. So I watched the Phantom Menace thinking it was the first ever Star Wars film. I didn't look at the year it was released, so I spent the whole film thinking 'this seems a bit modern for a 1977 film'.
Anyway, I finished Episode 1, and then went back to the start and watched Episode 4 and continued to watch them all in theatrical release order.
I don't know what the general consensus is about the films, but I feel like the story never really reached the heights of the original trilogy. The prequels were terrible, but the sequels, although clearly better, also fall way short of the originals. Revenge of the Sith was probably better than any of the final trilogy though, so the prequels has that going for it. Force Awakens was pretty good, but it got progressively worse with each subsequent film and now I kind of wish I hadn't bothered with any of it.
4, 5, 6 were great.
3 and 7 were pretty decent.
8 and 9 were bang average.
1 and 2 were genuinely awful
