**Contains Spoliers**
I completely agree that some of the additional footage adds to the coherence of the story. It definitely helped to make some of the characters more real.
As far as the Host is concerned I much preferred the version with the dog as I had always felt that the Alien took on the characteristics of its host, so it didn't make sense to now see it born from a totally different animal... Also in the "Assembly Cut" the dog still went missing but that plot line remained unresolved if I remember rightly...
My biggest complaint about Alien 3 however is not at all redressed in the new cut, and that is that it negates everything that happened to the characters that survived the ordeal of
Aliens - getting rid of newt and hicks in the credit sequence was just bad!
