The problem with tracing the Elton John lifetime in reverse is that we know it’s all fake and the vicious whip pans are used so you don’t spend enough time on younger Elton’s face to spot that it’s a series of lookalikes.
Consequently the viewer experience is like watching Elton perform from the seat of a rollercoaster.
It’s a mess.
The central idea has some merit, although I have to say the Christmas element is pretty minimal.
Now, if you wanna see an ad that tells someone’s life story in reverse in a believable and very moving way check out this far superior (and much cheaper) execution from Barnardos.
