The prequels were on the same level as the origibal trilogy - they were entertaining, yet mindless and terribly acted.
Thise who complain about the acting in the prequels - have you not seen the originals? My god. The acting in those films was an absolute joke.
I think Han Solo and Chewbacca were the only characters in the original trilogy that werent horribly acted.
If anything the prequels were probably more thought provoking then either TFA or the originals, and i felt the action scenes were also far superior.
Some of the scripting and acting was "roll my eyes" worthy, and Jar Jar (and the whole Gungan race) was annoying...but its not as of the originals were free of "rolling eyes" moments.
Hell if you look at some of the most iconic moments of the original trilogy, many of there are borderline laughable in retrospect. The "i am your father" scene was so poorly acted, and so terribly monotone on Darth Vader's part that it seemed like he didn't even care what happened to Luke. I thought the trilogy did a much better job of portraying Anakin/Vader as the wreckless, emotional and highly unstable person he is supposed to be. In the origonals he just comes across as an pretty indifferent guy with abad temper.
