Yes, YES, YES!!! No matter how bad the film is, I always watch the end titles, usually for the music. "John Carter" had great end title music. Anyway, some end titles can introduce some completely original music, so, often, they ARE worth sitting through. I left during the John Carter credits, which I normally don't do, because the music was exhausting. The recording quality of that entire score is amateur at best, which is par for the course on Giacchino scores. Cars 2 may be one of the worst offenders of the last several decades. Credits are too long these days, don't need to make it worse with listing the musicians.
