The Matrix Revolutions
When I was a kid this one was my favorite mostly because of the final battle & boss fight.
Then in my teens I still loved it but you know, I had more context and could comprehend the ideas in the film and plot points I never fully understood.
In my twenties I found myself feeling this was weaker, myself being more a critic; oh how well watched a cinefile I was then. So bloated, unnecessary fight, too much action etc.
But now watching it again in my early thirties I find myself again in awe of the trilogy and this conclusion.
