I've always liked Jerry Zimmer's Trek Wars, a score of truly epic proportions, may well be the only score in existence that is performed by a 250-piece orchestra and conducted by 2 different men at the same time, one on the stage and one behind a set of high end computers loaded with the latest tech in audio modulation software and all sorts of trickery to make orchestral music sound a little bit more electronic. Check it out, it's fantastic. Worst score I've ever heard is Goldsmith's (Interstellar Wars: The Motionless Movie), it features only 1,45 minutes of score, but I only like the first 15 seconds, with the little fanfare at the end. After that, it's just endless droning in the style of Hans Williams.
