Those movie titles are incorrect. They should be Kicking and SCREAMING, The ENIGMA of Kasper Hauser, Best in SHOW, The Prisoner of SECOND Avenue, and Three Little WORDS. So next I'm going to look at the synopses for the Screaming Enigma Show.
The second word of each synopsis says SHIFT CHANNELS BY NUMBER PLUS THREE. TGL is channel 4, so I'll Caesar-shift "TGL" by 4 + 3 = 7, and get "ANS." If I do that to each channel I get ANS WER ALL NEW, and indeed the answer is ALL NEW.
