Thank you, Andrew.
Honestly it's been so long since I've seen the theatrical cut, I probably couldn't make a fair judgment. Only scene I remember being added is Tuco meeting with his two outlaw buddies in that cove (prepping a chicken). Other than that, I barely remember where the additional 20 minutes are added. (And yes, I do recall the voice dubs during that extra scene being extremely strange.)
So, so good. An all-time fave.
