These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Jeff Wayne's Musical Version of The War of the Worlds
Narm: In the stage show, as shown in the 2006 live DVD. Most of the background film being synchronised with the music works really well, but the "dancing heatray" during Horsell Common looks a bit silly.
This is taken Up to Eleven in the New Generation stage show where not only is the heat ray seen "dancing" multiple times, but there are also two occasions where it thrashes around as if it was having an epileptic seizure. Luckily, they appear to have toned it back down a bit when they updated the film (again) for the Final Arena Tour.
