PAL and SECAM are also interlaced.

Except PAL/SECAM don't have any of the color issues of NTSC.

PAL's lower frame rate made for visible flicker, which viewers conditioned to NTSC could wearily detect.

Film is 24fps which is lower than PAL.

The 30fps of NTSC is actually associated with "cheap-looking" video.

NTSC's rate was 29.97 and its lesser line count made images seem blurry to those who were used to PAL and SECAM. Folks viewing PAL after NTSC felt that the flicker caused eye fatigue.
