I recently did a rewatch of the whole Star Wars saga (Episodes I-VI). I'd rank the films from best to worst as:
1. ANH
2. ESB
3. ROTS
4. ROTJ
5. AOTC
6. TPM
While I admit the Prequels are not perfect. I also think the OT isn't amazing as detractors of the Prequels claim.
TPM suffers from not having a main character and having a plot we the audience don't care about. If Obi-Wan had been the character we focused and followed throughout the film, I think it would be better. I think that's the biggest issue right there. The characters that everyone paid to see/cared about (the guys with the lightsabers) have very little effect to the resolution of the story.
I noticed and UGLY parallel between the
TPM and
ROTJ. I think they have a lot of the same problems.
Gungans made to appeal to children = Ewoks made to appeal to children. While the Gungans did have better tech to deal with the droid army, and actually seemed to be adept warriors. Jar Jar's idiot antics poisons the well for the whole batch. I'd rather that than the implausible defeat storm troopers suffered at the hand of 3 feet teddy bears. Like WTF.
Qui-Gon and Obi vs Maul = Luke vs Vader + Sidious: Their confrontation had no effect to the resolution of the plot. Seriously the guys with lightsabers are little more than supporting characters in their own movie. It's worse for
ROTJ because Luke and Vader were the characters we had been following up to that point from
ANH and
ESB. The scenes on Endor are longer and more prevalent than Luke's confrontation with his father and the Emperor.
Too many things going on in the final acts.
TPM:
Battle on Naboo (Padme)
Battle on Naboo( Jar Jar)
Battle in space (Anakin)
Battle on Naboo( Obi and Qui)
ROTJ
Battle on Endor (Han and Leia)
Battle in space (Lando) With a complete repeat of the space battle from ANH. Only this time the Death Star has an even more implausible weakness.
Battle on Death Star (Luke and Vader)
There are other things but I can't recall them atm.
With
AOTC is an ok movie. The love stuff is horrible but that is such a small part of the film. I think AOTC suffers from being the middle movie in a trilogy and being a check list film. AOTC sets up the clone wars but very little of the actual war is shown in the film. AOTC is also there to set up the part 3 of the prequel trilogy but doesn't have enough umph to make it standout.
AOTC comes off as a checklist film IMO. It has all the things people want to see in a Star Wars film.
Jedi using lightsaber
Big battles involving numerous Jedi
Storm Troopers
Space Battles
Boba Fett
Yoda fighting
Jedi fighting guys with red lightsabers
Battle droids
Tattoine
None of these are bad things but it just didn't make me care. I felt the same way about STID. It's a checklist of things people want to see in a Trek movie but nothing in it made me care.
ROTS really ironed out a lot of the bugs from the first two prequels. Aside from Lucas' shitty romance dialogue and Padme's death by losing the will to live. Anakin's fall is believable and the fall of the Jedi is so tragic. While Anakin was a whiner and a jerk at times. He did have his moments of heroism in the film. If anyone has seen the two Clone Wars series, there are more examples of Anakin being heroic there. Anakin is not as likable as Luke, i agree. However I do appreciate that Anakin is unique, and that Lucas didn't write Anakin to be Luke 2.0 for his prequels.
ROTS was a strong end to a rather weak series. Contrary to
ROTJ which was a weak end to an otherwise great series.
Follow-up
Compare how Anakin and Luke deliver these lines.
By this point Anakin had already fallen to the dark side and murdered dozens of Jedi (including children). Luke is warning Jabba not to take him lightly, and would later hack and slash Jabba's men to death. When Luke entered Jabba's palace he force choked two of the pig guards. Force choking is a dark move Jedi don't use. Luke was in real danger of falling to the dark side in ROTJ. Maybe if ROTJ had more scenes with Luke drifting closer to the dark side, it may have been a stronger movie.
