Can this movie be skipped, and only watch the other two?
One thing I've always thought about the PT is that Phantom Menace, while being lambasted as a poor Star Wars movie and a let-down for many millions after many years, is still an old-fashioned good vs evil adventure with exciting settings and diverse characters, even if a couple are annoying. It has a definite self-contained plot and battles galore, and ends with victory for the beseiged planet.
Revenge of the Sith, likewise, is an epic conclusion with quite dark themes, and many consider it the best of the PT, and it has many iconic scenes not to mention even bigger battles and saber fights. It neatly leads into ANH, or if you'd even like it to, Rogue One.
However, AOTC has always been my sticking point with the PT, as it's just so BORING. All this stuff about the Separatists and the cloners, and the awful love story between Anakin and Padme, as well as the other stuff, and even the battle is boring, and Count Dooku is not even that interesting. Also, not to mention Anakin's incessant WHINING and TANTRUMS. Yes, I would say that the plot of AOTC interests me the LEAST, and I actually think I could do without it in my collection.
So yes, I like TPM and love ROTS, and like AOTC the least. I don't have any physical media boxsets so I can buy the movies individually, so as of this moment, I only have ROTS in my collection, but I really think I will buy TPM and omit AOTC.
So in the end, my perfect Star Wars sextet would actually be the OT, the PT minus AOTC, and Rogue One, as I'm a huge fan of the Death Star. So that's what I will have.
