A few points to pick up on here:

I rate Back to the Future alongside Jaws, Star Wars, Close Encounters of the Third Kind, Raiders of the Lost Ark, E.T. The Extra-Terrestrial, and other childhood landmarks of the Spielberg/Lucas golden era. For me, they are all brilliant.

Spirited Away and Blade Runner are also major favourites of mine, so no argument there. Same with the first two Godfather films, Blazing Saddles, and Lawrence of Arabia (I agree it loses momentum in the second half, but it is still an iconic, one of a kind, must-see-on-a-screen-the-size-of-the-Sahara-in-70mm film).

Regarding The Last Jedi, this piece I wrote on it about three years ago may interest you (I consider it the best Star Wars film since the original trilogy):
