That's the trend of these type of shows. While these types of shows can/could be considered educational content, they try to over dramatize them to make them "entertaining". They try to build up some drama/tension even if it is obviously forced. Then intercut with the limited video footage you have even reusing the same footage. There's a fine line to keep educational content from boring your viewers to tears and making it feel like sitting in a secondary school class, but the producers have not gotten it right yet.
