I'd recommend these scores if you like thematic material:
John Williams - Jurassic Park, Indiana Jones and the Last Crusade
James Horner - The Land Before Time, Titanic, An American Tail, Willow
John Barry - Dances With Wolves, Out of Africa, The Scarlet Letter
Joe Hisaishi - Spirited Away, Princess Mononoke
Angela Morley - Watership Down
You can actually tell the types of scores people like just by reading who composes the pieces.
