If you look at all three trilogies, interest wanes during the course of each. The first film does the best, followed by the second and then third (well, ROTS did better than AOTC, but not better than TPM and ROTJ did better domestically than TESB, but not worldwide or adjusted for inflation). So the three top films are ANH, TPM and TFA. Well, if you want them in order by adjusted domestic gross, they are ANH, TFA, TESB, ROTJ, TPM, TLJ, ROTS, TROS, AOTC. While not the order I would rate the films, that is the order I rate the trilogies (OT, ST, PT). So the ST has been more successful than the PT was. Disney has a lot to be happy about… except Solo.
