It's hard for me to say which was worse. A full half of TLJ we just boring and also had some cringeworthy stuff. ROS isn't as easily dividable into boring and entertaining arcs, but it has some of the most cringeworthy plot ideas and moments of any Stat Wars movie. That said, they are both better than Attack of the Clones which was at least 90% boring and also had some of the most cringeworthy dialogue ever.
