If these beautifully made videos are intended for beginners in English, starting with "Hello!" and "I'm..." how are the learners supposed to understand all the explanations in English? Put another way, if the target learners are able to understand all the 'background explanations', then they can't be beginners in English! Compare this with the (very) old-fashioned British 'Follow Me" series, where new words are carefully introduced. There can't be 'false beginners' in oral English!
