This is absolutely a class A edit. The punched up- effects shots are very subtle for the most part and I could not always tell the difference but the differences I spotted were really great! Especially in the beginning rescue 15Maf has combined many favorite elements of mine from both cuts and it’s seamless.
Only bad thing I can think of is the running time which is slightly longer than Assembly cut. 2 and half hours is a long time to watch all those bald heads. =) Maybe some more cuts could be made to bring down the running time but I’m not sure what (don’t know the movie well enough for that).
All in all I think I’m watching this again instead of my bluray the next time I’m watching Alien 3. I think I would only go back to the theatrical cut if I want to see a more compact version.
