It goes without saying, too much inappropriate noise (so-called music)
More seriously, the program was very interesting, particularly in showing earlier disasters with steam engine boilers as an entertaining lead-in to the need for improved temperature measurement. Unfortunately these explosions had nothing to do with temperature measurement but rather with excessive pressure and failure to pressure test boilers, until a statutary requirement was enacted. Of course some failures were due to allowing dangerously low water levels . Fusible plugs were installed to counter high firebox temperatures by causing flooding to extinguish the fire. Temperature measurement was never used to control steam boilers in the 19th century or since.
Another example of lack of "prescision" is with electricity where there seemed to be a competition for measurement between the units in which the ampere won! What kind of misleading science is this?
