Now, I might be in the minority here, but while redux adds in some neat scenes, I really think the original release is the stronger film. I found a lot of the redux additions tonally inconsistent and detrimental to the build up towards the confrontation with Kurtz. But a lot of people think the exact opposite, and think the extra footage makes a richer story.
You probably watched it on Netflix a couple years ago, I remember showing it to my brother around then and I didn’t realize it was redux until like 40 minutes in, I thought I was losing my mind lol.
