That's not at all far off the mark in my estimation. My top five definitely includes Goodfellas along with these in no particular order:
Judgment at Nuremberg
Citizen Kane
Lawrence of Arabia
The Godfather
For anyone who's seen the film, make a point to beg, borrow or steal the book, Wise Guy. I read it on one night and I'm not a speed reader. It's that much of a compelling page turner.
It was a great film.
I would add Doctor Zhivago to the list, IMHO I consider it the greatest movie ever made, but Goodfellas certainly is up there.
Add The Shawshank Redemption- the feel good movie of all time.
