We have to consider that the recording equipment probably did not capture the detonation with much fidelity, and not at all the physiological effects of a powerful shockwave.
I was once fairly close to a lightning strike, and my impression was that there had just been a very loud bang - it was as if it had no duration whatsoever.
If a movie were to depict an explosion realistically, most of the audience would think there was something wrong about it.

I think that would be more applicable in the past, but now that there's plenty of real explosions you can see and hear on YouTube, a "movie explosion" probably sounds quite obviously... cinematic. The same goes for car crashes (which are in reality similar to your description of lightning: usually one loud bang, and then silence --- no tinkling of shrapnel or boomy bass echoes.)
