An overall uninteresting documentary about the work of the man "behind" Gaudi. Which could and should have been the title for it, maintaining a reference to the latter name, to draw attention, but not giving the same relevance as is.
Not that the title is particularly relevant to our enjoyment, but it illustrates the dissonance we go into it, as the documentary doesn't focus almost nothing on Gaudi and his work, beyond the initial known collaborations with Jujol.
If it's interesting for giving notice to the man usually lost behind Gaidu's recognition, it still isn't particularly well realised, consisting basically of several opinions of different people, pointing out his genius and process and not focusing as much in the relevance of his contrasting work within the remaining architectural and artistic work of the time.
