Both trilogies serve as prequels to a far greater trilogy. Both have had more of a mixed reaction to their respective fanbases. And now it is up to you to decide; which trilogy is better, the Hobbit trilogy or the Star Wars prequel trilogy?
Personally, my vote goes to the Hobbit trilogy. Despite the excessive CGI and visual effects, as well as the additional storylines and subplots, at least it feels as though it is from the same vein of movies as the LOTR trilogy. On the other hand, the Star Wars prequel trilogy completely sidelined the visual style and charm of the OT, resulting in a set of movies that have neither the humor, nostalgia, or feel of the original classic films. The Hobbit trilogy also has far superior acting.
Ultimately, the decision is up to you. Please vote in the poll above!
