Theatrical v Special Edition (Director´s cut)
I prefer the Director´s cut, even though some scenes I didn´t care for. The scene with Newt´s parents, slightly undermines the impact of finding Newt when we don´t know about her existence in the theatrical version. Hudson´s "check it out" scene is a bit dumb. On the other hand, I really liked the addition of Ripley finding out about her dead daughter, it adds an emotional gravitas to the Ripley-Newt relationship. The sentry gun scene is pretty awesome too and when they run out of ammo it adds to the direness of the predicament they are in.
