The flying in Superman
came across as shaky at best in 1978 - a few good shots, a lot of compromises and a few stinkers; no, I did not "believe a man could fly." I believed Christopher Reeve was Superman, though - Clark Kent, not so much.
As for three pages back...I'd sit through Serenity
again before I'd tolerate four of the six Star Wars
movies, and I do know a few things about film.
