In some cases are remake and original equally good
"Lady Vanishes" from 1938 (Hitchcock) and version from 1979, directed by Antony Page and with Eliot Gould & Cybill Shepherd (Angela Lansbury played vanished "Miss Froy"
I love the original, but the remake is modernised just as much the film needed.
On the other hand, some Hitchock's films didn't have any luck with TV-remakes, even when producers optioned for star casting
"Shadow of a Doubt" from 1943 had a poor remake for TV in 1991 with Mark Harmon, and "Rebecca" from 1940 had a dull remake for TV in 1997 with Charles Dance and such dames as Diana Rigg & Faye Dunnaway, who both (sadly) agreed to play, hm, grannies
(that was acting, that was method acting, or so called transformation)...
... and "Suspicion" from 1941 was remade as a 90 minutes episode for series "American Playhouse" in 1988.
What about Gus Van Sant's "Psycho" from 1998 with Anne Heche, Vince Vaughn, and Julianne Moore?
It's not a remake but rehearsal in editing.
