I wanted to watch Alien as I originally remembered seeing it back in the day before the various colour regrades of the modern releases. Someone kindly sent me Laserdisc rips of the theatrical cuts of all 3 films.
Yeah, this wasn't very good. It was very middling for most of it, but the dialogue and exposition gets worse and worse as the movie goes on. And then the weird changes to the story start to pile up and culminate in a baffling ending.
