Little Women - The Doctor knock some sense into Jo, and she accepts Laurie’s marriage proposal. Also, he cures Beth of Scarlet Fever before any real damage occurs. Amy goes on to become the next companion.
Pointless? Yes, but honestly I didn’t connect with that movie right anyway, and I sure as heck am not going to read the book.
Lovecraft’s “The Dunwich Horror”?
Infinite Crisis, TNG’s The Best of Both Worlds—or Assignment Earth :dubious:—and Cloverfield.
