Yep. The first has a shonky charm but it's all over the place as an actual film. The second is better made. The third is half good half shite.
I can only imagine the sort of reaction final-film revelations like "actually, it turns out they're brother and sister!" would get from modern, hyper-critical audiences. "They spent all that time building up the Emperor and then just kill him without giving us any backstory?!" Etc, etc.
Im not particularly fond of Star Wars, and it’s been ages since I’ve watched the prequels, but I found this film the most frustrating. There’s actually a good movie in there trying to burst free. It has some great elements in there and with a little more care and finesse it could have been a really powerful and interesting work.
