The best thing about POTC by a long way is the music. I would watch a fourth one for the music alone.
More Basil Poledouris (1946-2006) now. His best scores are all stirring military-inspired themes big on pomp and brass, but he also did gentler ones for stuff like The
Blue Lagoon and
Free Willy. I always thought he did
The Total Recall score but I just found out it was Jerry Goldsmith so that one will have to wait.
BONUS!
