My only problem with &quot;Cave of Forgotten Dreams&quot; was that it probably should have been an amazing 45 minute film, but he stretched it to twice that to make it into a feature. By the end, what was initially magical felt diminished by repetition.<p>In contrast, when I visited Grotte de Niaux [1], we were allowed only a brief moment to see the cave paintings to keep the cave temperature constant. That limited time was truly special.<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Cave_of_Niaux" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Cave_of_Niaux</a>
