Psycho (1960)
Directed by: Alfred Hitchcock
Written by: Joseph Stefano
Based on: Psycho (1959) by Robert Bloch
Why it’s better: The film subverts audience expectations by starting with the story of Marion Crane (Janet Leigh) instead of Norman Bates (Anthony Perkins), making her death a surprise and upping the suspense that has made Psycho a classic. Plus, Norman is a more complex and ultimately sympathetic character in the film.
The movie sucked
#25... I don't think better as such, but more so, brilliantly capturing the true essence of the books, yet Mr Tom bombadil is much missed
The movies are weak on it's own, but they are crap adaptation. It's plastic-cheap game cutscene-level, which is way more obvoius when you (try to) watch The Hobbit.
Overall you have very little idea on what makes movie better than book. Cutting things and simplyfying plot does not make them better story teller.
About the other books and movies that I've read and watch:
Godfather:
Both movies are great on it's own but it does not make them better than books.
The Prestige:
The book seems to be good until finale which is crap.
Movies are typical Nolan-like pulp, he's crappy storyteller.
Jurassic Park.
Movie is great on it's own, but book is much wider and Spielberg have to cut good part of it to make reasonable size movie. Other plots were included in part III.
As for Starship Troopers (I didn't read the book) - the movie was dumb. Satiric tone was nicely made (as Verhoven did in Robocop), but the rest was huge pile of crap.
