The tongue-in-cheek campaign, created by the consumer team at PR agency MHP, launched today ahead of this Sunday's Academy Awards ceremony.
The video (see below), shot by Sassy Films, captures the honest reactions of 10 children as they watch trailers for some of the biggest films of the last year.
TalkTalk TV managing director Aleks Habdank said: "We all already know what the Hollywood experts think, now it's time to get the view from real people - and who better to tell it like it is than kids?"
One child describes a kissing scene between La La Land lead actors Ryan Gosling and Emma Stone as "cute but disgusting", while another summed up the film as "gross".
The kids can also be seen trying to correctly pronounce the name of American actress Meryl Streep, with one getting as close as "metal steep".
TalkTalk TV launched the campaign to coincide with many of the films appearing on its service throughout the year, and to highlight a discount promotion on previous award-winning films that it is currently featuring, said MHP director Mark Perkins.
