Love for The Mission definitely spans many generations. Even the famously ego-centric (see above!) Rosenman admitted that it deserved the Oscar, even though it was up against Rosenman's TreK IV score. Zimmer also called it a favorite and admitted to ripping it off on several occasions.
Carter Burwell has cited Forbidden Planet as one of his favorites.
In Bernard Herrmann's famous 1972 Sight and Sound interview, he cited THE BROTHERS KARAMAZOV (1931) by Karol Rathaus, IVAN THE TERRIBLE by Prokofiev, and several scores by Vaughan Williams and Walton.
